Thank you, Sandy. Good afternoon, everyone. For Q1 fiscal 2020, net sales, as expected, decreased 18% sequentially to $131.4 million. In Q1, shipments into Asia represented 78% of net sales. North America represented 12%, and Europe represented 10%. Total direct sales represented approximately 38%, and sales to distribution represented approximately 62%. Our distribution business remains balanced, with 54% of the total POS coming from high-end consumer and enterprise computing end markets, and 46% of total POS coming from the industrial and communications end markets. Q1 bookings improved nicely Q over Q and resulted in a book to bill above one. Those bookings accounted for approximately 47% of shipments during the quarter.
As expected, Q1 fiscal 2020 GAAP gross margin increased 10 basis points sequentially to 61.9%, while Q1 GAAP operating expense declined 5% sequentially due to the one-time benefit from the reduction in the fair value of contingent earn-out obligations and lower intangible amortization expense. In Q1, GAAP interest and other expense was $1.4 million, an increase from the $548,000 in Q4 that had benefited from a $1.3 million gain on the sale of an investment. Q1 GAAP tax benefit of approximately 20.3% was driven by the discrete tax benefit from Comcast exercising its remaining warrants. We expect our GAAP tax rate for the rest of fiscal year 2020 to be in the range of 15%-19%. Our GAAP tax rate forecast excludes consideration of any impact from discrete items, including excess tax benefit or deficiency from exercise of stock options.
Moving on to the non-GAAP results, which exclude the impact of share-based compensation, amortization of acquired intangibles, acquisition-related or other non-recurring charges. In Q1, non-GAAP gross margin increased 10 basis points sequentially to 62.2%, as expected, and we expect Q2 non-GAAP gross margin to remain flat. In fiscal year 2020, we expect our gross margin to remain stable, driven mostly by end market mix. Q1 non-GAAP operating expense was $53.1 million, flat with Q4, as higher payroll expense was offset by lower new product spending due to timing. In Q2, we expect non-GAAP operating expense to be flat or decline 4% sequentially because of lower variable compensation expenses driven by lower revenue expectations. While maintaining our investments in our key growth drivers, we expect our non-GAAP operating expenses for fiscal year 2020 to be approximately flat or only modestly higher with the prior year.
We expect our fiscal 2020 non-GAAP tax rates to remain in the 15%-17% range. In Q1, cash flow from operations decreased sequentially due to lower net revenue and annual disbursements for supplemental compensation. Our stock repurchase authorization stands at approximately $181 million. We expect to continue to use our cash to opportunistically repurchase our shares, make strategic investments, and pay down the debt. In Q1, accounts receivable decreased 16% sequentially due to lower net sales and represented 50 days of sales, which is above our target range of 40-45 days. In Q2, we expect accounts receivables to increase, but for days of sales to return within our target range. Net inventory in absolute dollar terms increased 15% sequentially, and days of inventory increased to 125 days, which is above our target range of 90-100 days.
In Q2, we expect our net inventory to be up in absolute dollars and days to be flat due to the export restrictions on a key customer and the expectations for higher sales in the second half of the year. In summary, we were able to achieve our Q1 expectations in a difficult macro environment. Bookings grew strongly sequentially as we are seeing early signs of inventory levels in several markets beginning to normalize. While the recent geopolitical challenges from the export restriction are contributing to near-term customer uncertainty and impacting our revenue, we will continue to focus on execution and believe the long-term secular nature of our growth engines position us for a stronger second half of fiscal 2020. I will now hand the call over to Mohan.
Thank you, Emeka. Good afternoon, everyone. I will discuss our Q1 FY 2020 performance by end market and by product group, and then provide our outlook for Q2 of fiscal year 2020. In Q1 of fiscal year 2020, net revenue decreased 18% over the prior quarter to $131.4 million. Weaker overall global demand environment in all our end markets contributed to the decline. We posted non-GAAP gross margin of 62.2% and non-GAAP earnings per diluted share of $0.34. In Q1 of fiscal year 2020, net revenues from the industrial market declined and represented 30% of net revenues. Net revenues from the enterprise computing end market declined and represented 27% of revenues. Net revenues from the communications end market declined over the prior quarter and represented 10% of total net revenues.
Net revenues from the high-end consumer market increased 13% over the prior quarter and represented 33% of total net revenues. Approximately 25% of high-end consumer net revenue was attributable to mobile devices, and approximately 8% was attributable to other consumer systems. Our Q1 high-end consumer revenues were impacted positively, as expected, by Huawei's increase in demand, which we believe was a result of them increasing their chip inventories in anticipation of a potential ban. I will now discuss the performance of each of our product groups. In Q1 of fiscal year 2020, net revenues from our signal integrity product group decreased 30% over the prior quarter's record results and represented 38% of total net revenues. As expected, demand decreased across all of our target market segments, including the data center, PON, and wireless base station markets.
In Q1 of fiscal year 2020, data center demand declined as cloud and hyperscale data center providers further reduced inventory levels. Our ClearEdge CDRs continue to do very well in new 25 gig to 100 gig NRZ-based optical modules and active optical cables. We believe customer inventory levels are returning to more normalized levels and demand forecasts from our data center customers and bookings have started to improve. In fact, our signal integrity products group recently received the largest-ever single order for our ClearEdge CDRs for a North American mega data center customer. During Q1, our initial Tri-Edge PAM4 CDR samples experienced strong customer interest, as its low cost, low power, and low latency characteristics are ideal for 50 gigabit per second, 100 gigabit per second, 200 gigabit per second, and 400 gigabit per second PAM4 applications. We recently announced our participation in the formation of the OpenEye Multisource Agreement.
The OpenEye MSA, launched with 19 initial member companies, targets low cost, low power, and low latency PAM4 optical modules using analog PAM4 CDRs, such as Semtech's Tri-Edge platform. We expect to see our first Tri-Edge PAM4 revenues starting in Q4 this year. Our FiberEdge PMD platform, which complements our Tri-Edge and ClearEdge CDR platforms, continue to be qualified at key module customers, where we have collaborated with the leading DSP providers for use in next generation 100 gig, 200 gig, and 400 gig PAM4 optical module solutions. Our FiberEdge platforms have garnered strong design win traction, and we are seeing initial modest revenues from 100 gig PAM4 modules and from 400 gig PAM4 modules. We expect these modules to begin to ramp to volume beginning in FY 2021. In Q1 of FY 2020, PON demand declined sequentially as expected.
Our PON demand is largely driven by China, where demand has softened over the last two quarters. Semtech continues to be the PON PMD market leader, providing highly integrated solutions for one gig, 2.5 gig, and 10 gig PON ONU and OLT platforms. We currently expect stronger second half PON demand as PON tenders for this year in China indicate unit volumes similar to calendar year 2018 volumes. The medium-term impact of the Huawei ban on our PON demand will not be clear for another quarter. Our wireless base station demand was also weak in Q1, and we expect this business to also be negatively impacted in Q2 due to the Huawei ban. For FY 2020, we expect to see further spending on 4G deployments, as well as the ongoing ramp of 5G platforms throughout the year, with stronger growth expected in FY 2021.
We remain excited about our market opportunity for 5G base stations, which we believe could more than double from 4G due to larger volumes and additional content as we expect most optical links to require CDRs. Despite the current challenges faced by our signal integrity product group in this fiscal year, we remain very confident in our strategy and expect our SIP product group to grow nicely over the next few years, driven by the ongoing expansion of cloud and hyperscale data centers, the global transition to 5G base stations, and the acceleration of 10 gig PON deployments. For Q2 of fiscal year 2020, we expect net revenues from our signal integrity product group to be approximately flat. Moving on to our protection product group.
In Q1 of fiscal year 2020, net revenues from our protection product group declined 8% over the prior quarter and represented 30% of total net revenues. Demand from all end markets remained relatively weak in Q1. Our automotive protection business gained momentum in Q1 and reflects a need for high-performance protection used in advanced driver assistance systems. Semtech's superior protection performance, including that of our recently announced RClamp 3552TQ, enables our customers to offer enhanced robustness for infotainment systems incorporating ADAS functions. Newer high-speed interfaces such as USB 3.1 Type-C, 10 Gig Ethernet, and HDMI 2.1 are rapidly proliferating across all end markets and applications. As a result, we see growing demand for our high-performance protection platforms that address these interfaces.
Our protection product group remains focused on diversifying from the high-end consumer market to the broader industrial markets, where there is an increasing usage of more advanced topography devices. We believe our investments in these broader markets will enable us to diversify our business over the next few years. In Q2 of fiscal year 2020, we expect our protection business to increase as demand from the broad-based industrial end market is expected to recover. Turning to our wireless and sensing product group. In Q1 of fiscal year 2020, net revenues from our wireless and sensing product group decreased 9% sequentially and represented 32% of total net revenues. Weaker demand from the industrial end markets contributed to the decline. Despite the recent softness in our wireless and sensing business due to a weak China demand environment, we do expect to see improving demand throughout the rest of the year.
Our LoRa momentum continues to build. We are seeing very exciting momentum across the globe, underlined by some of the key LoRa metrics we track. These include the number of public or private LoRa network operators increased in Q1 to approximately 113 from 100 at the end of fiscal year 2019. We now expect 130 LoRa network operators by the end of fiscal year 2020. The number of countries with LoRa networks grew to more than 74 countries. By the end of fiscal year 2020, we expect over 90 countries to have LoRa networks. The estimated number of LoRa gateways deployed increased to more than 300,000. These gateways will support approximately 1.5 billion connected end nodes. We expect the number of LoRa gateways deployed to exceed 500,000 by the end of fiscal year 2020, supporting a LoRa end node capacity of over 2 billion end nodes.
The estimated cumulative number of LoRa end nodes deployed increased to approximately 197 million. We expect this number to exceed 140 million by the end of fiscal year 2020. The LoRa opportunity pipeline increased to over $450 million of LoRa-enabled opportunities in our pipeline, with an additional $200 million of leads feeding the opportunity pipeline. We anticipate that on average, 40%-50% of this pipeline will eventually convert to full deployment over a 24-month timeline. In addition to the strong performance on our LoRa metrics, we also began to see a number of new exciting use cases and new ecosystem partners. Some examples of this are Target announced its use of LoRa to improve retail operations and retail guest experience at the IoTFuse conference in Minneapolis. SAP recently announced the integration of LoRa into its Leonardo IoT platform to support LPWAN industrial IoT use cases globally.
MachineMax, a revolutionary wireless telematics company, announced its LoRa-based machine sensing system for construction and mining systems, enabling significant fleet management and efficiency improvements. Ineo-Sense, an emerging leader in wireless industrial sensing applications, announced its LoRa-based sensing system to monitor and track manufacturing assets in facilities exceeding 100,000 sq ft. Sonova, a leader in advanced hearing aid technology and solutions, announced its latest IoT connected hearing aid, which uses LoRa to deliver best-in-class wireless performance. Our pipeline of opportunities includes many new use cases, which include very high volume and very disruptive use cases for numerous industry segments. We will discuss these use cases in future earnings calls as they move from opportunities to proof of concepts and design wins. We recently announced the release of our first cloud-based LoRa microservice.
Our first microservice is a LoRa-based geolocation service that is available to our partners and customers to track and locate their LoRaWAN devices using the cloud. The interest in the service has been very high. We are starting to demonstrate the unique value of a LoRaWAN-based asset tracking system to our global ecosystem. We believe that we will start to have customers transition from testing the service to full qualification and commercialization of their services by Q4 of this fiscal year. We expect our LoRa microservices to grow to between $80 million-$100 million in revenues within the next five years. Our wireless and sensing product group continues to focus on developing ways to enable the faster proliferation of LoRa.
Specifically, in Q1, we started to offer a full suite of hardware reference designs, software building blocks, and a suite of development tools and services that will enable solutions providers and system integrators to move from concept phase to end deployment more rapidly. In addition to these new platform development tools, we have also accelerated our LoRa Design Partner Program and our LoRaWAN Academy program. Both of these programs have been specifically designed to simplify the development and deployment of LoRa-based solutions and accelerate the time to market of total IoT solutions based on LoRa. Both programs already have large global interest from the developer and academic communities.
In FY 2020, despite the broader macro concerns and soft demand from China, we still expect our LoRa-enabled revenues to be between $100 million and $140 million. We continue to expect LoRa to become the de facto standard for LPWAN use cases over the next few years in what we expect to be a multi-billion unit industry. In Q1 of fiscal year 2020, demand for our proximity sensing platforms increased and delivered record quarterly revenues due to strong demand from Huawei and increasingly stringent global SAR regulations. We believe our proximity sensing business should continue to expand as we see solid design win progress in new customers and regions as global regulations drive an increase in the need for radio energy management on smartphones and other mobile devices.
In addition, as 5G smartphones start to enter the market during the year, we expect to see an increased number of high-performance radios, which drives higher proximity sensing content in these devices. For Q2 of fiscal year 2020, we expect net revenues from our wireless and sensing product group to be approximately flat. Moving on to new products and design wins. In Q1 of fiscal year 2020, we released 11 new products and achieved a record 2,884 new design wins. Now let me discuss our outlook for the second quarter of fiscal year 2020. Despite the strong improvement in our recent bookings, based on the near-term geopolitical uncertainty and the recent ban on shipments to Huawei, we are currently estimating Q2 net revenues to be between $128 million and $142 million.
To attain the midpoint of our guidance range, or approximately $135 million, we needed net turns orders of approximately 34% at the beginning of Q2. This Q2 guidance reflects a reduction of approximately $7 million due to anticipated reduced shipments and associated reduced demand related to the Huawei ban. We expect our Q2 non-GAAP earnings to be between $0.32 and $0.40 per diluted share. I will now hand the call back to the operator. Sandy, Emeka, and I will be happy to answer any questions. Operator?
At this time, I would like to remind everyone, in order to ask a question, please press star followed by the number one on your telephone keypad. We'll pause for just a moment to compile the Q&A roster. Your first question comes from the line of Karl Ackerman with Cowen.
Hi. Good afternoon, everyone. Thanks for taking my question. Emeka or Mohan, perhaps to start off with, I'd like to focus on your LoRa business. What % of your LoRa business today is from your own chip sales versus licensing or royalty revenue from third-party chip sales by your analog and mixed signal partners? I guess as we contemplate your revenue funnel ramping from here, what's the right way to think about the mix of royalty revenue versus your own chip sales and then the, of course, commensurate impact on your margin goals? Thank you.
Karl, pretty much most of the revenue is going to come from our chip sales for the next couple of years. And chips for both end nodes and for gateways. I think from a licensing standpoint, the licensing royalties from partners will start to pick up over the next few years. I would say it still will take another couple of years. Microservices revenues will start to increase next year. As I said, it'll take, I think, a few years for that to really become material. Initially, at least for the next couple of years, I think it's still predominantly chip sales, both end nodes and gateway sales.
I appreciate that. If I could ask just one more question. Clearly, the revenue headwind from Huawei and the inventory overhang at distributor customers is impacting your margins near term. However, you've spoken on this call about a recovery in the second half. How should we think about the progression toward your long-term 34% operating margin target? I guess, is there a certain revenue level we need to achieve that, or are there certain efficiency programs and product mix that should help us attain that goal? Thank you.
Karl, thank you. I think we've stated before that a lot of the path to the midpoint of the revised operating margin range is going to be driven by top-line growth. We've done really a very good job of managing our operating expenses, and our gross margins are really very stable. We've also indicated in the past that we would expect to see about $750 million-$800 million of annual revenue for us to get to that midpoint of that range. That is how we look at it at this point. Clearly, the top-line growth is going to be the key driver in that leverage expansion.
Karl, if you look back at Q3 of FY 2019, we had essentially 30% operating margins. That's kind of the range of revenue that we need to get to.
Your next question comes from the line of Harsh Kumar with Piper Jaffray.
Yeah. Hey, guys. First of all, very good execution and very good commentary in light of all this macro weakness. Mohan, I'm going to put you on a spot. The last earnings call, I think you mentioned you're looking for a pretty steep hockey stick-like. You might not have used that term, but a pretty steep ramp in the second half. I'm curious, with another quarter under your belt, and given what all you're seeing in China and macro level, what would be your best guess if you want to just give some color around how you expect the second half to go?
Yeah. Harsh, I think if absent the Huawei ban, I would still be suggesting that bookings are strong. We have seen China weak for a couple of quarters now, but demand is picking up. Our LoRa business is going great. We see data center demand, inventory levels, as I mentioned on the call, starting to become more in line, and we're start seeing a pickup in orders on the data center side. If I look across the different end markets and product lines, I think the second half is still looking quite strong. For us, obviously, the Huawei ban puts a little bit of a spanner in the works, and we have to work through that, both the direct impact and also the indirect impact.
Absent that, I would suggest that the second half is still looking to be quite strong relative to the first half, for sure anyway.
Very good. Mohan, if I can ask you, there's Huawei, which is one animal that you don't have control over. I'm still curious. Your bookings sound really good. I was curious if you could differentiate or comment on bookings out of China, ex Huawei or outside of Huawei, and provide us any color. Are you still seeing ebbing or flatness there, or are you seeing a flat out ramp ex Huawei in China?
Excluding Huawei, which obviously it's a big part of the China demand, excluding Huawei, I would say that China demand has been soft for the last couple of quarters. We're starting to see some improvements in that area. That's kind of promising, of course with all of the uncertainty associated with the tariffs and now Huawei. How long that can be sustained, I don't know. At least from our perspective, that's what we've been seeing, a little bit of a pickup in the rest of the China demand, like in China industrial and some of those other use cases.
Hey, just one last quick one. The $450 million funnel for LoRa, is that including the $100 million you expect from services or excluding that?
We don't have any services at the moment in there, Harsh. The way we look at opportunities and the way we measure our pipeline, these are real proof of concepts and real opportunities that our customers are working on. Now, with the geolocation, we've just announced that service. We now have customers who are starting to look at that. I would say that that is in addition to the $450 million plus $200 million pipeline leads.
Thanks, guys.
Thank you.
Your next question comes from Quinn Bolton with Needham & Company.
Hey, guys. Wanted to just first ask on the Huawei exposure, can you give us some sense sort of where you're exposed across signal integrity, protection, wireless, and sensing, and specifically, is there any exposure to Huawei on the LoRa business? Then I've got a follow-up on the data center side of the business.
First of all, on the LoRa business, there's no exposure to Huawei. Huawei is actually one of the key proponents of the NB-IoT, so it's really a competitor to the LoRa solution. Most of our exposure, Quinn, is on the signal integrity product side. I would say on the PON base station side, those two areas. Then there's some exposure on the protection side for smartphones for Huawei. That's predominantly where the exposure is. We don't see much exposure anywhere else. There's both a direct and an indirect exposure. The direct exposure is what we ship directly to Huawei and through HiSilicon. Then the indirect is really through other module companies. Also when Huawei can't get components to build its system, which we learnt from the ZTE ban a year ago, that could have a negative impact on us.
We've tried to quantify that as best we can. Obviously, they're all estimates and approximations until we really see what happens through the quarter. It gives you an idea.
I know you're not guiding beyond the July quarter, but if I just look at the ban that went into effect May 21st, you might have been able to ship approximately three weeks before Huawei went to a ban. If we're trying to think about what the Huawei impact for future quarters might be, if there's no resolution, would a full quarter effect be more likely in the, say, $8 million-$9 million range? Is that a good ballpark for a full quarter basis?
Yeah, we think between $6 million and $10 million is a good range. That's what we see today. Obviously, we'll learn a lot over the next quarter, but that's kind of what we're projecting.
Great. On the data center business, in the script, you mentioned receiving the largest order in the company's history for the ClearEdge 25G CDRs from a North American data center customer. Just wondering if you could provide a little bit more color on that application. I assume that's probably for a CWDM4 100G module type application. Just wondering if you could give us a little bit more color on that design win or that order.
Other than the 100G CWDM4 and that it is a North American data center customer, that pretty much nails it, right, Quinn? I think I can't really give you a lot more color other than this is a customer that has been looking at PAM4 solutions and other solutions and decided some of the optics weren't ready and concluded that it's going to stick with NRZ module for now.
Great. Okay. Thank you.
Our next question is from Gary Mobley with Wells Fargo Securities.
Hey, guys. Thanks for taking my question. It's great to be on the call for the first time. A question about Huawei. I appreciate the fact that it's certainly a shock to the supply chain, a shock to Semtech, and certainly takes, what, $7 million of revenue away from the second quarter. Presumably at some point, somebody's going to pick up the slack of Huawei can't ship. Somebody on the Android smartphone front will pick up the slack. Somebody on the 5G base station infrastructure might pick up the slack. ZTE perhaps on the PON side might pick up some share. How are you positioned with the alternatives to Huawei, and how do you see sort of the shock of Huawei going away and transitioning to other customers?
Yeah, that's a good question, Gary. I think, first of all, we are well positioned with most of the other players in these segments. Until we see the orders, until we see the demand, it's very difficult to anticipate what will happen. In ZTE's case, we use the example where they initially thought that they were going to be able to build a system. They realized they couldn't build a system, and then it wasn't until they started to realize that, hey, they are short of some components or some part of the system that their customers started to look at alternative solution providers. We started to see orders being picked up from other places. I think we're in good shape, but we just don't know. Until we see that material orders coming in, we just can't make that assumption, right?
Your OpEx guidance for the second quarter appears to be flat to down slightly and flat for the overall year. It appears as though you're managing OpEx by just simply having less bonus accruals, perhaps, and maybe some other items. Is there any consideration to maybe being a little more streamlined on some R&D activities, maybe making some deeper cuts to OpEx to get back to the target operating margin level? Is this just going to be a top-line recovery story?
Gary, I think it's just going to be a top-line recovery story. You're new to the story, you haven't been here in the past when we had much higher levels of operating expenses. We've already done a lot of the things that you've talked about. We've pruned a lot of our expenses. We've refocused our strategies in some areas and making sure that we're focusing on product areas that are very high levels of return on investment. Having said that, we know about 20% of operating expenses is still variable. Like you did say, a lot of that is tied on the supplemental compensation. We do have some room in terms of what we can do. Clearly, the runway that we used to have in the past is no longer as much as what we used to have.
The other point I'd add to that is that most of our investments are platform type of investments. We're investing for the next generation of LoRa platform, the next generation 400G optical platforms for next generation of protection platforms. They're not investments that are short-term in nature. Most of our investments are much more strategic.
Okay. Thank you, guys.
Your next question comes from Mitch Steves with RBC Capital Markets.
Hey, guys. Thanks for taking my question. First I'm going to focus on the gross margin line. Since Huawei doesn't really have the high-end LoRa product, should we assume that gross margins improve sequentially starting July to October to January?
Huawei doesn't have any LoRa revenues at all, I'm trying to understand the connection between Huawei, LoRa, and gross margins.
If you have no Huawei-
No, Mitch, most of our Huawei business is PON, base station, and smartphone related.
No, that's my point, right? Basically we know that there's no high-end, high margin business there. Doesn't that mean the gross margins go up October to January?
Well, I think we just have to see how everything comes in the mix. What we've said in the past is that we expect our gross margins to be stable. We would expect it to have a little bit of an upward bias, but we have to see how everything comes in before we know exactly what happens with gross margin. The expectation here is that our gross margins will be stable going forward.
Okay. Yeah, the second question, just on the China exposure. We get the Huawei number at 6%, right? If I look at the China exposure to Asia, you're showing like 70%, but that's a ship to number. Is there any way to at least give us qualitatively what the actual official sell to China is, versus just the 78% Asia Pacific number you guys give out?
Yeah. What we've said, Mitch, is that our shipments to China overall are about the 50%-55% range. We've said on prior calls that if you look at that as to what's actually probably consumed in China, it's probably closer to the mid 30%-upper 30% range.
Okay, perfect. Thank you.
Your next question comes from Craig Ellis with B. Riley FBR.
Yeah, thanks for taking the question. Mohan, I wanted to ask you a longer-term question. I know it's an environment where we've got limited visibility, but the question's intent is really understanding better some of the company specific drivers that exist in the portfolio. Harsh asked you about the second half. My question really ties back to some of your comments on signal integrity data center business and the business more broadly. It sounds like there's a PAM4 and a PMD product ramp coming as we head into calendar 2020, fiscal 2021. The question beyond that is what do you see in the rest of the business that you're excited about that's driving Semtech's growth as we look beyond what is clearly a cyclical and trade dispute characterized year this year?
Well, I think, Craig, first of all, just on the SIP business, on the signal integrity product business, obviously we have the 100G to 400G growth. We also have the AptoVision ProAV video over IP technology that we believe that's got good future growth. Outside the signal integrity product group growth engines, of course, we have LoRa, which is really doing quite well, continues to grow, and I think will largely continue to grow regardless of the type of geographical issues we're seeing because it's really tied to IoT, which is really tied to efficiency improvements and just broad cost reductions and things like that. Just the whole growth of IoT is driving that. We think that that's going to continue for many years. Obviously, that's very exciting for us.
The proximity sensing is tied to global regulatory requirements for managing radio power in devices, so we think that will continue to grow. As I mentioned in protection, our business of industrial kind of driven strategy now versus the just pure consumer and consumer-driven strategy, I think is really quite exciting because we see more advanced lithography devices going into more systems outside just smartphones and handhelds and consumer devices. Into automotive, into communications equipment, into IoT. Those require the kind of high-end protection that we deliver. We have a number of different growth drivers that are really independent of whatever's going on in China, independent of the Huawei ban, that I think are going to continue to allow us to drive good growth in the future.
I think that's helpful. The follow-up question is just on LoRa. If my tally was correct as you walked through the different milestones, it seems like the business is performing to all five milestones that you talked about on the last call. One of the things you pointed to was an increase in LoRa's business mix outside of China this year. One, is that still the expectation? Two, any further color on just milestones and how you're thinking about the company's progress?
Yeah. First of all, it is the expectation that we will start to get a little bit more balanced geographically. I will tell you, our China LoRa business is going very well. It's a question of can the other regions continue to outgrow what's happening in China. I think that we have good momentum. We look at all these metrics, not just for the purpose of is the business going in the right direction, but what things we need to do in the business to accelerate in certain areas, certain bottlenecks. That's one of the reasons I pointed out that we've made the conscious decision to invest in and enhance the ability for our customers to accelerate their time to market from going from a proof of concept to actually having deployment.
That means more software, more design tools, more reference designs, having the availability of partners, developer platforms, and things like that. We put a lot of emphasis on that. I think we'll continue to see that this year. I think that the momentum, as I said, as the opportunity pipeline has increased still further, which is great news for us. I think if we can start to move some of that pipeline to revenue over the next year and a half here, I think we're going to be in very good shape.
Thanks, Mohan.
Your next question comes from Tore Svanberg with Stifel.
Yes, thank you. First of all, a question back to Huawei. Sounds like $6 million-$10 million. If you look at your last quarter, it says it's about $21 million. Should we just assume that half of that was kind of just inventory build, and it's more the run rate that's going to be $6 million-$10 million going forward?
That's correct, Tore. It was clear that, and I mentioned it on my script, that Huawei had built inventory mostly for smartphone business in Q1, which definitely inflated that Q1 number. They may even have built up some inventory from Q3 or Q4 of last year, more tied to the PON and base station business. Yeah, I definitely think that the run rate number, you should look at it as a run rate number, the $10 million.
Thanks for clarifying that. As a follow-up, you guided the wireless and sensing business to be flat sequentially. I assume that means maybe some of the smartphone business is going to be down, LoRa will actually grow sequentially.
That's correct. The proximity sensing was one of the areas that we believe Huawei has built inventories in Q1, that'll be down in Q2, LoRa is expected to have very good growth in Q2.
Great. Just one last question. You said data center bookings are improving, you talked about that one win, is this broad-based enough now where maybe data center could actually grow sequentially in the July quarter?
Data center is I think it's possible. I think it's probably likely to be flat and then maybe start to increase in the second half. We are seeing some good data points and some good bookings in this area.
Okay. It feels like that business has indeed bottomed here the last two quarters.
Yeah. It's starting to feel that way.
Great. Thank you very much, Mohan.
Your next question comes from Rick Schafer with Oppenheimer.
Yeah, thanks. I just had a couple questions. I guess the first one may be a follow-up on LoRa. Mohan, I think you've talked in the past, I think about LoRa potentially being a $1 billion-type revenue stream looking forward three to five years. I guess, is that still a realistic target in your mind? Then, as part of that answer, I'm curious when you see the revenue crossover. I know you talked earlier about licensing versus chip sales. Sort of when do we see that seesaw kind of crossover?
Well, I think let's take that one first, Rick. I think for next couple of years, still it will be mostly chip revenues, I think. I would expect probably three years from now, the royalties, both from chip licensing and from services to start to kick in nicely. I expect those to accelerate quite quickly, especially on the services side. Coming back to the volume, the size of this business and how can it scale. One of the reasons I talk about these metrics and I point out, for example, the end of this fiscal year, we expect to have 500,000 gateways out there, is because each one of those gateways supports a certain number of sensors, and therefore, the capacity to support 2 billion end nodes.
The 2 billion end nodes, if you translate even at $0.50 an end node is $1 billion, right? To me, I think it's a question of once the infrastructure is deployed, once the use cases are in place, and once there's enough of a smooth runway from proof of concept to deployment, which is one of the things we're working on now, I just think it's a matter of time. A question of how many use cases and can some of them be very high volume, which I believe they can. I think we're starting to see a lot more use cases now that are potentially very high volume. Before it was more industrial in nature, now we're seeing more smart home, more smart enterprise and smart consumer kind of things emerge as IoT potential LoRa targets.
Got it. Thanks. Just another follow-up on data center. Can you remind us what CDR attach or just what overall attach, whether we're talking about CDR, PMD attach looks like at single lambda 100G versus 25G? Maybe part of that answer, just give us a sense of what Semtech content can do.
For CDRs, for 100G and above, pretty much all of the modules will require some type of CDR functionality. That's also true of base station. As we see base stations now starting to deploy faster optical links, we think most of those will also require CDR functions. That's been our thesis for a while. We are definitely seeing that happen.
Okay. Can you talk about dollar content and maybe a sense of-
It varies $5 to $10, I think, on average, Rick, depending on the type of module, PAM4 versus NRZ versus different reaches. It really varies, but I think, typically $5 to $10 is the ASP.
Great. Thanks a lot.
Our next question comes from Christopher Rolland with Susquehanna.
Hey, guys. On inventories, if Huawei doesn't come back, will these be fairly easy to ship to other customers? You mentioned proximity sensing. Is there good demand there from other customers? When might inventories normalize? Thanks.
Yeah. Most of our products are standard products. Some of them are application specific, but they're not customer specific in general. There may be a couple of million USD of inventory that may be targeted specifically for Huawei, but in general, I would say that they're for a broader set of customers.
Yeah, Chris, in terms of when inventory normalizes, our expectation is that beginning with Q2, we should start to see the days of inventory coming down. By Q3, especially if we see the uptick in revenue in the top line that we're expecting, we should expect to see inventories come back down to our normal levels.
Great. Then, on the signal integrity side, for base station in particular, can you guys talk about your exposure to the various OEMs outside of Huawei? Is it all Huawei? What % of shipments here are not Huawei, and how do you expect that to ramp through the year? Thanks.
We have good exposure to other customers, the majority of the volume for us anyway so far has been driven out of China. Obviously Huawei is the big guy there for us. We have exposure to other Chinese base station manufacturers, of course, some of the European. I would say the volume is driven for us, mostly out of Huawei.
Thanks, guys.
Okay, our next question is from Tristan Gerra with Baird.
Hi, good afternoon. Question on LoRa. Obviously you guys have very good traction in industrial applications. That's including smart metering. What does it take for LoRa to gain momentum in the IoT U.S. market? We still see a lot of Wi-Fi and DECT technologies in IoT. Is there a kind of a catalyst that will create an inflection point for us to see more LoRa-based IoT devices in the U.S. mass market?
That's a good question, Tristan. I would say that a lot of the opportunities we have are in North America, and some of them are high volume. It is starting to emerge. I think the home is an important battleground for LoRa in the smart home, and I think that's one that we've just started to really spend some calories on and understanding what it's going to take there. Some of our partners are helping us in that area. I think the other thing in the U.S. is the U.S. has a large enterprise space in terms of smart buildings and smart asset tracking and logistics type of systems. We are starting to learn more about how some of those systems and those verticals are going to use LoRa and how LoRa can really transform the way that those industries work and operate.
That's kind of part of what I said about how it's important for us to understand how these opportunities translate to full proof of concepts and then how the proof of concepts move through to design wins and then through to revenue. Understanding where the friction and where the bottlenecks are and removing those. Some of those are software, for example, and some of those are applications. We're learning more about that, and I think that's part of the reason why you're seeing a lot of emphasis from us on the tools we're bringing to market to allow our customers to move faster through that process. I think you're going to see North America over the next couple of years really become a very nice revenue driver for LoRa.
Okay. As a quick follow-up, you've talked about LoRa revenue increasing sequentially in your guidance, and you've also talked about, in general for your whole business, about your initial expectation for the second half. Regarding LoRa specifically, would you say that for now, revenue is tracking about in line with normal seasonality? Or is the reiteration of your full year guidance, embedding an expectation that your second half is going to need to be seasonally stronger than it's been in the past?
Definitely the latter, Tristan. I think, if you recall, it's partly what I've been saying about China. LoRa has been doing extremely well in China, and we started to see that softness in Q4. It's nothing related to IoT or LoRa. It's really just a China demand softness issue for us. We are starting to see signs that's now picking up. I think the second half, we do expect it to be strong based on the metrics. Based on opportunities and design wins and real momentum we see. Now, how strong it's going to be, whether it's as strong as we're expecting, or whether it's going to push out to the following fiscal year, to me, it really doesn't matter that much.
I think it's more a question of the fact that once we have this momentum, there is going to be a catalyst at some point that takes this from being a $20 million, $30 million, $40 million a quarter run rate to a $100 million a quarter run rate.
Great. Thank you very much.
Your next question comes from Scott Searle with ROTH Capital.
Hey, good afternoon. Thanks for taking my question. Mohan, to follow up on the LoRa front, I just wanted to clarify, I'm not sure if I heard it. Were LoRa revenues up sequentially? The mix, it sounds like China was a little seasonally weaker. Is China less than 50% of the mix? As part of that, looking out to the year, you're maintaining the guidance for the year of $100 million-$140 million. The metrics all seem like they're in line in terms of what you articulated a couple of months ago, things seem like they're tracking. It's still a pretty wide variance, though, considering that we've got eight months to go in the fiscal year.
I'm kind of wondering what the potential big swing factors are that get you to the higher end of the range versus lower end of the range. It basically implies that revenues are doubling probably from where you were in the current April quarter. Thanks.
I think that's a correct assessment, Scott. To me, the way to look at it is that these opportunities we have in the pipeline, it's really a question of calling when they're going to translate into revenues and how fast. We don't have exact data, right? We just look at it and say, okay, these design wins are ramping now, and they're going to full deployments. We can see that they're going to materialize in the second half, and we're expecting stronger revenue from that. It's a very broad range of use cases, and it's a very more balanced regional flavor as well. Coming back to your question on China. China has been, I think, over 50%, I can't remember exactly the number, of our LoRa business. Clearly it's been a significant contributor to our LoRa revenue.
With the China softness, that has impacted our LoRa enabled revenue. As I mentioned, we have enough pipeline, as long as those opportunities convert, we'll still be able to achieve our goal this year, which was a reduced goal to $100 million-$140 million. It's still early on in the fiscal year, we'll see how that plays out. We're starting to see some good momentum now, both on the revenue front and also on the conversion rate from opportunities to revenue.
Hey, just lastly, if I could follow, Mohan, that doesn't include any tags. There's no expectation for tags kicking in this year, right? That's more fiscal 2021 and beyond, correct?
That's correct. Yeah.
Okay. Thank you.
Our next question comes from Hamed Khorsand with BWS.
Hey, thanks for taking my questions. Just two here. First off, with the data center stabilizing, would you expect to regain some pricing control, or are you just happy managing the business for gross margin?
Well, I think, Hamed, we don't look at it as there's so many different use cases, and the way this works typically is we're selling into module manufacturers. The module manufacturers have to reach a certain cost per gigabit that they're trying to achieve for the end customers. So one of the advantages, of course, we have with the ClearEdge family is the NRZ modules and the components and the optics related to those are much cheaper. So we are probably being as aggressive as we need to be there. On the PAM4 stuff, we probably don't need to be as aggressive, and so it's really dependent on each situation.
Okay. My other question was on the automotive side, with new models coming out, do you have any design wins on deck as we get into the second half of the year when new models start shipping from the auto manufacturers?
I know we have a lot of design wins on the protection side. We have some on the LoRa side. I don't know exactly the timing of those, to be honest with you. I think they typically take a lot longer than 12 months for qualification. We have good momentum with our protection business in the automotive space.
Is it the revenue that you're reporting from automotive, is that all just trial based then? Not commercial?
No, the revenue on protection, on the revenue that we are talking about is revenue. On the numbers we talk about, when we talk about automotive numbers, it's real revenue. I'm talking about the ramp of other additional automotive opportunities.
Okay. Got you. All right. Thank you.
Our last question comes from the line of Craig Ellis with B. Riley FBR.
Thanks for sneaking me back in for one more question. Mohan, I just wanted to follow up. The company's got a real nice $100 million net cash balance. You've certainly got the flexibility to repurchase shares. Does the uncertain macro cause you to think any differently strategically about how you deploy that cash? Do tech tuck-ins or other deals look any more appealing in this environment?
No, Craig, I know we're not thinking differently about that at all. The reason we don't think differently is because we still have very high expectations for the future. We still believe very much in the secular nature of the growth drivers that we have, our LoRa platform. We believe that the build-out of the hyperscale data centers is going to continue. We believe that the PON deployments transitioning to 10 gig is going to continue. These are all markets where we're very nicely positioned. Despite the current macro headwinds that everybody is seeing right now, we still very much believe in our future and what we have to deliver. We're not thinking about it any differently. Having said that, we always remain to look to be really opportunistic with our buyback. We have $181 million authorized.
If the opportunity is there, we will continue to buy back our stock, but also continue to make the strategic investments that will continue to assure our future.
Got it. Thanks, Emeka.
There are no further questions at this time. Your closing remarks, please.
In closing, despite the near-term uncertainty driven by the macro and geopolitical environment, we remain confident in the underlying strength of the secular drivers behind our growth engines, which we believe are clearly intact. We see early indications from our customers that suggest a stronger second half fiscal year 2020, despite the slow start to the year. With that, we appreciate your continued support of Semtech and look forward to updating you all next quarter. Thank you.
