Thank you, Sandy. Good afternoon, everyone. For Q4 fiscal 2019, net sales were $160 million, an 8% sequential decline and an increase of 14% from the same period a year ago. Fiscal year 2019 net sales were a record and an increase of 7% over the prior year, driven by our diversified growth drivers in the IoT, data center, and mobile markets. In Q4, shipments into Asia represented 74% of net sales, North America represented 18%, and Europe represented 8%. Total direct sales represented approximately 32%, and sales to distribution represented approximately 68%. Our distribution business remains balanced, with 53% of the total POS coming from high-end consumer and enterprise computing end markets and 47% of total POS coming from the industrial and communications end markets. Q4 bookings softened Q over Q and resulted in a book-to-bill below one. Those bookings accounted for approximately 45% of shipments during the quarter.
Q4 fiscal 2019 GAAP gross margin increased 40 basis points sequentially as expected to 61.8%, while Q4 operating expense increased approximately 11% sequentially, due mainly to the non-recurrence of a one-time benefit from reduction in the fair value of contingent earnout obligations in Q3. In Q4, GAAP interest and other expense was $548,000 and benefited from a $1.3 million gain on the sale of an investment, compared to $31.2 million of expense in Q3, which included the $30 million in payment of our modified investment. Q4 GAAP tax rate was approximately 49%, driven by a discrete item related to acquisition-related intangibles. The excess tax benefits of Comcast exercising its remaining warrants will drive our Q1 GAAP tax rate to a benefit in the range of 8%-12%. We expect our GAAP tax rate for the rest of fiscal year 2020 to be in the range of 20%-24%.
Moving on to the non-GAAP results, which exclude the impact of share-based compensation, amortization of acquired intangibles, acquisition or disposition related, and other non-recurring expenses. Note that as previously disclosed in our first quarter fiscal year 2019 earnings call, we no longer adjust net sales for the impact of the Comcast warrant for any comparable historical periods presented. Instead, we have provided a separate disclosure of the impact of the Comcast warrants on the financial statements in our Form 8-K filing and our press release. Q4 non-GAAP gross margin increased 40 basis points sequentially to 62.1% as expected, due to a more favorable product mix. We expect Q1 non-GAAP gross margin to increase slightly as the benefits of improved manufacturing efficiencies are offset by a higher mix of high-end consumer revenue.
In fiscal year 2020, we expect our gross margin to remain stable with an upward bias driven mostly by end market mix. Q4 non-GAAP operating expenses was $53.1 million, down 2% from Q3, driven by lower variable compensation expenses. In Q1, we expect non-GAAP operating expense to decline between 2% and 6% sequentially, as a result of lower variable compensation expenses driven by lower revenue. We expect our non-GAAP operating expenses for fiscal year 2020 to be approximately flat sequentially, while maintaining our investments in our growth drivers. In Q4, our non-GAAP tax rate decreased slightly to 15.6% sequentially, and we expect our fiscal year 2020 non-GAAP tax rates to be between 15% and 19%. In Q4, cash flow from operations increased 22% over the same period a year ago to $47 million or 29% of net sales.
For fiscal year 2019, cash flow from operations increased 65% over fiscal year 2018 to $184 million or 29% of net sales, and represented a new record. Free cash flow was 27% of net sales for both Q4 and fiscal year 2019, and in line with our upwardly revised target range of 25%-30%. In Q4, our cash and investments was flat at $312 million, and our debt balance was approximately $212 million, resulting in a net cash position of $100 million. We repurchased approximately 771,000 shares of $36.5 million of stock in Q4, and $2.4 million or $116.2 million in fiscal year 2019. Our stock repurchase authorization now stands at approximately $181 million. We expect to continue to use our cash to opportunistically repurchase our shares, make strategic investments, and pay down our debt.
In Q4, accounts receivable decreased 5% sequentially due to lower net sales and represented 46 days of sales, just above the target range of 40 to 45 days. Net inventory in absolute dollar terms increased 4% sequentially, and days of inventory increased to 93 days, which remains at the lower end of our target range of 90 to 100 days. In Q1, we expect net inventory to be up in absolute dollars and days on lower Q1 sales and expectations for higher sales in the remainder of the year. In summary, we are pleased with our strong financial performance in fiscal year 2019. Our net sales grew 7% year-over-year to a new record, while we grew our non-GAAP earnings almost twice as fast, a demonstration of the solid leverage in our operating model.
Operating cash flow was also a new record. We repurchased 2.4 million shares or 3.7% of our issued and outstanding stock in fiscal year 2019. While the geopolitical and macro issues echoed by our peers is contributing to near-term headwinds and a slower start to fiscal year 2020, we will continue to focus on execution and believe the long-term nature of our growth engines positions us nicely for recovery, beginning with the second quarter and strengthening into the second half of fiscal year 2020. I will now hand the call over to Mohan.
Thank you, Emeka. Good afternoon, everyone. I will discuss our Q4 fiscal year 2019 performance by end market and by product group, discuss our fiscal year 2019 performance, then provide our outlook for Q1 of fiscal year 2020. In Q4 of fiscal year 2019, net revenues decreased 8% over the prior quarter to $160 million. Seasonal inventory reductions in the high-end consumer end market and a weaker global demand environment contributed to the weakness in Q4. We posted non-GAAP gross margin of 62.1% and non-GAAP earnings per diluted share of $0.55. In Q4 of fiscal year 2019, net revenues from the enterprise computing end market increased over the prior quarter and represented 33% of total net revenues. Revenues from the high-end consumer end market decreased over the prior quarter and represented 24% of total net revenues.
Approximately 16% of high-end consumer net revenues was attributable to mobile devices, approximately 8% was attributable to other consumer systems. The industrial and communications end markets also declined over the prior quarter and represented 32% and 11% of total net revenues respectively. I will now discuss the performance of each of our product groups. In Q4 of fiscal year 2019, net revenues from our Signal Integrity Products group increased 2% over the prior quarter, achieved a new quarterly record and represented 45% of total net revenues. Demand increased for our PON products, while demand from the data center and the wireless base station markets were flat with the prior quarter. In Q4, data center demand for our industry-leading ClearEdge CDR platforms used in high-performance 25 gigabit per second to 100 gigabit per second NRZ optical modules and active optical cables remained healthy.
We also sampled our first Tri-Edge CDR platform for PAM4 interfaces targeted at 200 gigabit per second and 400 gigabit per second PAM4 optical modules. Initial customer feedback is very positive in applications which require the highest performance at the lowest cost and lowest power. We expect to see initial Tri-Edge revenues in the latter part of this year. Our FiberEdge PMD platforms, which complement our ClearEdge and Tri-Edge CDR platforms, are targeted at next generation 100G, 200G, and 400G optical modules, and also sampling and receiving positive customer feedback. Our FiberEdge platforms include linear drivers and TIAs that are partnered with industry-leading DSPs and provide a seamless interface to PAM4 optics.
We expect to maintain our leadership position in the optical module market as data center customers transition from our 100G ClearEdge NRZ platforms to 200G and 400G PAM4 optical modules using our FiberEdge and Tri-Edge platforms later this year, with real growth expected to begin in FY 2021. In Q4, demand for our PON products increased sequentially. Semtech is a PMD technology leader in the 1G, 2.5G, and emerging 10G PON module market. We recently introduced several new PON platforms leveraging our FiberEdge PMD technology that we believe will enable us to extend our leadership position over the next few years as the market transitions to 10G PON. Our China base station business also remained healthy in Q4, driven by demand from both the 4G and 5G markets.
We are excited about our prospects in the emerging 5G build-out and expect these networks to utilize Semtech's full portfolio of high-performance CDRs and PMD devices. We expect early 5G base station implementations to initially use our ClearEdge and FiberEdge platforms with 25 gigabit per second front haul and back haul links, then transition to our Tri-Edge PAM4 CDRs in FY 2021. For Q1 of fiscal year 2020, we are seeing a much weaker demand environment due to excess data center inventory, China market demand softness, and uncertainty associated with ongoing geopolitical issues. These issues are impacting near-term demand in all our target markets. As a result, we expect net revenues from our signal integrity product group to decline significantly in Q1 on lower demand across all end markets.
We do not expect this weakness to be sustained for more than a couple of quarters due to the ongoing expansion of hyperscale data centers globally, the global transition to 5G base stations, and the acceleration of 10G PON deployments. We remain very confident in our strategy and our position in our target markets and expect all our target markets to grow nicely over the next few years. Moving on to our protection product group. In Q4 of fiscal year 2019, our protection product group declined 21% over the prior quarter and represented 26% of total net revenues. Demand from the high-end consumer market weakened throughout the quarter, driven by year-end inventory reduction efforts and lower global demand for smartphones and other consumer equipment.
Despite the softening smartphone demand, our design wins across all tier 1 customers in all regions continues to do very well, we do expect to see a stronger second half performance from our protection smartphone business. We remain focused on diversifying our protection revenues by expanding from our strong position in the mobile market into the industrial market, which includes the automotive, IoT, and broad-based industrial segments. We expect our new investment in these segments will enable us to grow our protection business in industrial applications, which are increasingly used using advanced lithography devices. As an example, we recently announced the MicroClamp 2492SQ, which offers high performance protection for controller area network buses used in automotive and industrial applications. Future Ethernet ports, USB ports, and infotainment electronics within the automotive and industrial environments will likely all require higher-end protection.
In Q1 of fiscal year 2020, we expect our protection business to remain soft due to weak global demand from the smartphone market and weak China demand. We still expect our protection product group to deliver growth in FY 2020, despite the very challenging start to the year for our smartphone business. Turning to our wireless and sensing product group. In Q4 of fiscal year 2019, net revenues from our wireless and sensing product group decreased 9% sequentially, increased 22% over the same period a year ago and represented 29% of total net revenues. Seasonally lower demand from the smartphone and industrial end markets led to the decline. Q4 was another quarter of solid progress for our LoRa business.
A few of the key announcements in Q4 included Veolia and its subsidiary, Birdz, chose Orange Business Services to connect Veolia's 3 million intelligent water meters in France over the next 10 years using the Orange LoRa network. Semtech's SX126x LoRa transceiver platform was named the Analog Semiconductor of the Year at the Elektra Awards. The LoRa Alliance announced that there are now over 100 global LoRaWAN network operators. These are just a few of the many LoRa-related milestones announced during the quarter. In Q4 of fiscal year 2019, demand for our proximity sensing platforms decreased due to smartphone softness following several quarters of strength.
We do expect our proximity sensing business to continue to grow as we see solid design win progress across all regions as global regulations drive an increase in the need for radio energy management on smartphones and other mobile devices. In addition, we also see an increase in the number of high-performance radios and an increase in the power required from these radios, which supports increased proximity sensing content in mobile devices in the future. For Q1 of fiscal year 2020, we expect net revenues from our wireless and sensing product group to decline due to continued smartphone weakness and continued China demand weakness. Moving on to new products and design wins. In Q4 of fiscal year 2019, we released 28 new products and achieved 2,303 new design wins. Let me comment on our fiscal year 2019 performance.
In fiscal year 2019, Semtech delivered a record financial performance, with total net revenues increasing 7% over fiscal year 2018, driven by strong momentum from our three business units. We also achieved a record non-GAAP earnings per diluted share and record cash flow from operations. In FY 2019, we released 70 new product releases and achieved another new design win record of 9,317 new design wins. In FY 2019, our Signal Integrity Products group achieved record net revenues, driven by record CDR, record PON, and record PMD revenues. Our wireless and sensing product group also achieved record revenues, driven by record LoRa-enabled revenues and record proximity sensing revenues. Finally, in FY 2019, our protection product group grew 3% to deliver a solid annual performance as we continue to successfully diversify into new verticals. In FY 2019, Semtech's LoRa business achieved record results, with LoRa-enabled revenue increasing over 85% from FY 2018 to approximately $78 million.
In FY 2019, we were pleased to exceed nearly all the metrics we targeted at the beginning of the year. These metrics included the number of public or private LoRa network operators doubled from 50 at the end of FY 2018 to over 100 by the end of FY 2019. We expect at least 125 LoRa network operators by the end of FY 2020. The number of countries with LoRa networks grew to more than 70 countries from 50 at the end of FY 2018. By the end of FY 2020, we expect over 90 countries to have LoRa networks. The number of LoRa gateways more than tripled to 243,000 deployed gateways at the end of fiscal year 2019, up from 70,000 at the end of fiscal year 2018, and exceeded our expectation of 220,000 gateways. These gateways are now capable of supporting over 1.2 billion connected end nodes.
We expect the number of LoRa gateways deployed to double in FY 2020 to over 500,000, enabling a LoRa end node capacity of over 2 billion end nodes. The cumulative number of LoRa end nodes increased to 87 million at the end of FY 2019, from 50 million at the end of FY 2018. We expect this number to continue to grow rapidly and exceed 140 million cumulative end nodes by the end of FY 2020. The LoRa opportunity pipeline exceeded $400 million at the end of FY 2019, with an additional $200 million of leads feeding this pipeline. We anticipate that on average, 40%-50% of this pipeline will convert to full deployment over a 24-month timeline. In addition, while historically some 50% of our LoRa-enabled revenues have been from China, our opportunity pipeline has over 70% of the opportunity being driven from outside China.
As these opportunities convert to revenues, we expect our geographical revenue balance for LoRa to diversify. In FY 2020, despite the broader macro concerns and extremely soft demand from China, we still expect our LoRa-enabled revenues to be between $100 million and $140 million. In addition to the strong performance on our LoRa metrics, we also began to see a number of new exciting use cases. Some examples of this are Amazon's introduction of its Ring LoRa-based smart lighting system that enables lighting control and security around the perimeter of a home or enterprise targeted at the smart home and smart building segments. Comcast's MachineQ announcement with Victor to introduce VLINK, a smart LoRa-based rodent trap that communicates trap activity to its IoT network targeted at the smart home and smart building segments.
Tata Communications announced that together with Genesis Gas Solutions, they have won a contract with IGL in India to deploy prepaid smart gas meters using Tata Communications' LoRaWAN network. We expect Tata Communications to win many more smart metering contracts across India. While still in its early stages, Tata Communications' LoRaWAN network is expected to eventually cover over 400 million people in India. In the future, we expect to see an increasing number of similar applications where LoRa's low power and longer range can be leveraged in consumer and industrial IoT applications. This morning, we 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 use with their LoRaWAN solutions to track and locate their LoRaWAN devices using the cloud.
We believe that this service will be the first of many that we offer and will provide further value to the LoRa ecosystem. We expect our LoRa micro services to grow to between $80 million-$100 million in revenues within the next five years. Along with the LoRa Alliance, we expect to continue to drive LoRa to become the de facto standard for global LPWAN use cases in what we expect to be a multi-billion unit industry in the next five years. Let me discuss our outlook for the first quarter of 2020.
Despite a marked improvement in our bookings in the last two weeks, based on our backlog entering the quarter and continued softness from China, including a 30% decline in our quarterly POS forecast from China, and continued softness from the smartphone and data center markets, we are currently estimating Q1 non-GAAP net revenues to be between $125 million and $135 million. To attain the midpoint of our guidance range, or approximately $130 million, we needed net terms orders of approximately 40% at the beginning of Q1. We expect our Q1 non-GAAP earnings to be between $0.30 and $0.36 per diluted share. I will now hand the call back to the operator, and Sandy, Emeka and I will be happy to answer any questions. Operator?
At this time, I would like to inform everyone, in order to ask a question, please press star then the number 1 on your telephone keypad. Again, that'll be star then the number 1 on your telephone keypad. Will just pause for just a moment to compile the Q&A roster. We have your first question, comes from the line of Tore Svanberg from Stifel. Your line is now open.
Yes. Thank you. Mohan, can you elaborate a little bit on what you just said about a pretty sharp improvement in orders the last couple of weeks? Is that a broad-based comment? Is it specific to China? I'm also very interested in if it also refers to the data center market.
It's broad based, Tore. I haven't got the details of how much is related to data center, but I would say it's broad based. It's across all markets, all businesses, all regions.
Very good. Could you also update us on the LoRa pipeline, what you're expecting for maybe FY 2020? Obviously, it stood at 400 plus in FY 2019. Do you have a number for FY 2020?
Yeah. I expect it to end at $600 million in opportunity. The $200 million of leads that I mentioned that are in front of the pipeline, I expect to convert to opportunity. Some of the opportunity obviously will become revenue, but we see more and more leads emerging. I would say by the end of FY 2020, we'll be somewhere between $600 and $700 million in opportunity.
Great. Thank you. I'll go back in line. Thanks.
Your next question comes from the line of Craig Ellis from B. Riley. Your line is now open.
Hi, guys. Carlin Lynch here on for Craig. Thanks for taking our question. I just wanted to get some more clarity on the data center business, in particular, how you guys see that playing out in the second half of the year. I know you guys had talked about a bit of an inventory digestion in the first quarter before. I'm just wondering if you see that kind of moving through and if there'll be any marginal improvement on, say, a trade resolution. Thanks.
Yeah. The data center business, our customers tell us by mid to end of Q2, they expect the orders to start picking up again. They do see inventory there, but they expect that to come back. We know that there's still pretty big ambitions in terms of hyperscale data center build-outs across the globe. We do expect that to be predominantly a first half issue. Obviously, the trade issues give us a lot of concern because China is a big opportunity for us, both from a demand standpoint, but also from the fact that they generate a lot of the build plans for our customers in other regions. Just a lot of angst about placing orders and things like that. Any resolution for sure will just clear up the uncertainty and help customers take more risk, I think, which is important at this timeline.
If I could just ask a follow-up. You guys talked about a positive mix shift for you guys' margin. I was wondering if you could touch on or give a little more clarity on what's driving that mix and where you guys see margins moving throughout the year, even as you have maybe a bit of a disappointing first quarter.
With regards to the mix, what we see is our data center revenue rebounding in the second half. We see LoRa continuing to strengthen as we go through the year. We see more contribution to revenue from our video platforms. We see more contribution to revenue from our protection in industrial and automotive design wins. Clearly, we do see a lot of the revenue growth going forward coming from the higher gross margin end markets like industrial. That is why we do believe that we should expect to see our gross margins stable, but also inching up nicely as we go through the year.
Awesome. Thank you so much.
Your next question comes from the line of Harsh Kumar from Piper Sandler. Your line is now open.
Hey, guys. Thanks for letting me ask a question. Mohan, I had a simple question. If I was to take the $160 million you did in January, and try to sort of bridge it up to the guide of, call it, $130 at the midpoint, how would you characterize that gap across your different kind of end markets or product line? You mentioned that business seems to have stabilized, actually looking up very nicely in the last two weeks. In terms of ramp continuing through the rest of the year, how do you see the rest of the year? Previously, I think you guys have made a statement that FY 2020 could be flattish, possibly even up. Does that still hold true? I've got a follow-up.
Let me start with that first, Harsh. I think it still does. I think it's going to be tight, but I think it's still potentially flat to slightly up. It depends a lot on the second half. The way we look at the year currently is Q1 obviously is very soft. Q2 will start to improve, we are expecting a stronger second half, obviously. By mix of business, to kind of bridge to the Q4 number, majority of our weakness is in our Signal Integrity Products area. A lot of weakness in data center, a weakness in PON and base station also. Also, China across all of our businesses is weak. There's no question about that. As I mentioned, POS is down significantly in China.
That has an impact on all of our businesses, frankly, wireless, our LoRa business is a significant business in China. China handsets also, related to our SIP business. We do expect, as that starts to get better, if China improves, obviously that will be a positive for us. Those are the main drivers of the weakness in Q1.
Fair enough. For my follow-up, Mohan, I wanted to ask about LoRa. I think you mentioned $100 million and $240 million for this year, which is a little bit off from your previous estimates. Now, given that they were put out three or four years ago, we get that. Is that predominantly a function of what's going on in China and what you're seeing here? Also, is your additional $200 million of leads, does that include tags or microservices in it, or is that just pure chips?
Yeah. The leads and opportunities are all related to chips, including tags. Tags are chip-related products. Not microservices. That goes in a different bucket for us. Coming back to the range, it is really significantly impacted by China softness. We have been seeing a deterioration, I guess, midway through Q4, in our China business overall. As I mentioned, the POS has come down significantly. That has changed things. That's one of the reasons I mentioned that the opportunity pipeline, 70% of that is outside of China. The LoRa balance, I think, from a regional standpoint is going to shift nicely. That's going to take a little bit of time.
Now, bear in mind, the $100 million-$140 million in FY 2020, if we achieve the midpoint of that range, would still be up, LoRa would be up 56% or 54%, something in that range. Which is significant in the market environment we're in. As things improve through the year, I'll obviously keep you updated.
Okay. Thanks for the color, Mohan.
Your next question comes from the line of Mitch Steves from RBC Capital Markets. Your line is now open.
Hey, guys. Thanks for taking my question. I think the kind of the consumer and data center first half part makes sense, but I guess the first one I think that's kind of coming up a lot in conversation is just how do you guys get comfortable in the back half ramping up in terms of a year-over-year basis if you're seeing slowdowns, particularly in China, especially if there's no resolution on the trade side yet?
Yeah, that's a good question, Mitch. I think the China, we have to break it out into where we have business in China, and the China phenomenon is not really under our control, not much we can do. There is China softness in demand softness from the region itself, and then there's the uncertainty around all the geo situation. I think the China demand uncertainty, the China demand situation is kind of the biggest piece of it at the moment. We do expect that to start to see some improvements as PON gets deployed and base stations, more base stations get deployed and our customers are still telling us that they're planning to do that. We don't see a change there. Data center is the same. Our customers are still talking about deploying lots of larger scale data centers, but there is inventory at the moment.
Those give us indication that the second half is probably going to be stronger. How much stronger is a good big question. If I look at the other businesses, smartphone, for example, we're starting to see a little bit more positive kind of trends there. As I mentioned, the bookings over the last two weeks have strengthened, so that kind of supports some of that. LoRa is going to continue to do very well. We're absolutely convinced of that. We have a lot of opportunities, and the pipeline is shifting over, and it's just about execution and transition and timing on that.
Okay. Yeah, just to follow up there. I think the LoRa one makes sense, essentially it's just the timing of what quarter it comes in. When I look at the two kind of bigger debate points in the semi space have been smartphones or data center. Of those two, within your guidance of talking about, call it, flattish for 2020, which one are you guys more comfortable with in terms of growth, the smartphone side or the data centers side?
Yeah, I would say it's more based on what happened in FY 2019, and smartphones was not so strong in FY 2019. I think that there's a good chance it will be stronger, particularly if China and North America do better. The smartphone business, as you know, it can be tricky. One of the things that's in our favor in smartphone is we have a little bit more content now with not just protection, we have also proximity sensing. Data center, I do think, though, is an inventory issue, and that's why once the inventory, I think, works its way through in Q1 and maybe some in Q2, we'll start to see that pick up. At this point, I would say that probably smartphone is going to be a little bit stronger, and then data center depends on the second half.
Okay, perfect. Thank you.
Your next question comes from the line of Quinn Bolton from Needham & Company. Your line is now open.
Hey, guys. First, a clarification on the LoRa business. Did you say in fiscal 2019 that LoRa was probably 40%-50% China-based, but international or non-China was 70% of the design pipeline? Just want to make sure I got those numbers right.
Yeah. In FY 2019, that's our last fiscal year, Quinn, about 50% of the revenues, it's an approximation, but about 50% of the revenues was driven out of China. The opportunity pipeline, as we look at it, 70% of that is driven by outside of China. A large part of that's North America, but other regions outside China also. As we see those transition into revenue, we should see a little bit more diversification in our geographical revenue balance of LoRa, which I think, the only reason I point that out, or make a point of that is because China is very weak at the moment.
A follow-up, Mohan, on LoRa. You gave us some very specific guidance for the number of networks, the number of countries, greater than 500,000 gateways, greater than 140 million cumulative end nodes. The revenue range of $100-$140 is fairly wide. If you hit those metrics on networks, countries, gateways, end nodes, does that kind of put you towards the middle of the $100-$140? Does that get you to the low end? Does it get you to the high end? Just some sense of if you're tracking to the milestones you give us, does that kind of put you at the midpoint of the range, or better or worse?
Yeah, I would say it's better, Quinn. If we hit the milestone, particularly the cumulative end nodes deployed. Gateways and networks and countries doesn't necessarily translate to revenue. It's the conversion of the opportunities into real deployments that translates into revenues because the end nodes are really what drives the revenues. I would say the cumulative end nodes, though, if we hit 140 million, I think it will take us closer to the high end than the midpoint.
Perfect. Just lastly, I know we had OFC last week. You guys were in your quiet period, so you probably didn't get a chance to see a lot of investors. Any particular highlights you want to share with us, whether it's Tri-Edge, or just other products in the optical space?
Clarity around our strategy and confirmation that I think we have a very good strategy, and execution is key. Most of our customers recognize the value of our current ClearEdge family, and that continues to do well despite the current short-term issues with data center inventory and things like that. As we look forward, I think the consistent theme is high performance but at the lowest power and the lowest cost. We're having our Tri-Edge family out there now, being able to talk to customers as we're sampling for both 200 gig modules, short-reach modules, eventually longer-reach modules, eventually, combined with other platforms to provide really a roadmap for our customers, I think is very good for the PAM4 plans.
The FiberEdge family, which, as you know, supports DSP partners, I think is a really good platform and is starting to get design wins also. In general, we found it a very good show. It's just confirmation of our strategy, and I think we feel good about it. You add onto that the growth of 10 gig PON and the direction that PON is going in, which is more higher bandwidth, which is also good for us. The base station side as well, again, confirmation that high-speed links for front haul and back haul, which will need CDR functionality, I think is also confirmation. More of the same. I think also, talking to the customers about China and the weakness, I think confirmation there that the first half is going to be weak in general.
Great. Thank you for that, Mohan.
Your next question comes from the line of Tore Svanberg. Your line is now open.
Yes. Thank you. Just a few follow-ups. First of all, Mohan, as we think about the data center recovery in the second half, I know it's hard to quantify, but how much of that is kind of the market coming back versus some of these new programs? And I'm thinking especially the PAM4 CDRs for 200 and 400, because my sense is that's probably more of a fiscal 2021 event, but just want to understand.
No, that's correct.
As that comes back, how much is going to be market?
Yeah, that's correct, Tore. Most of the PAM4 stuff is going to be latter part of this year and into next year. It's all market-driven. It's all inventories being used up and some of the hyperscale stuff continuing to build out. It's a pretty global statement, I think, on data centers. I think we've seen China start to pick up, again, with the China softness, that's muted. I do think that it's more driven by market dynamics. I don't think it's specific to PAM4.
Okay, very good. You sound pretty upbeat on more operators globally on LoRa. Any sort of anecdotes that you can share with us there as far as Because I'm obviously thinking about the comparisons that are always made, right? Between NB-IoT and LoRa and some of the other WAN technologies out there. I don't know if there's anything you can share with us as far as anecdotes you've had with or conversations you've had with operators that really want to move more meaningfully with LoRa.
Yeah, I think, I kind of alluded to some of those on my prepared remarks, Orange's win with Veolia is a significant milestone for an operator. Very significant, actually, over a 10-year period. That's one. If I made some comments on some new use cases, Comcast with MachineQ's Victor rat trap or rodent trap connectivity. That one is a very interesting use case that I think has a global application. Obviously, the Amazon Ring discussion on their smart lighting. These are use cases that are really going to drive more demand for some of the operators. Tata is another one where winning a gas metering LoRaWAN use case in India, it kind of paves the way for them to then win many more similar types of use case wins, whether it's gas metering or water metering or whatever. That's great for the operators.
The operators that have joined the LoRa Alliance and have built out LoRaWAN networks or have obviously taken risks, they've built out network or have put their name behind it, and are now looking for use cases and real demand. That's really key for us, and that's one of the reasons why I put emphasis on the LoRa cloud service because it's very unique. This is not something many companies can do, and I don't think it's going to be something that you'll see from any chip companies. It's a very unique capability that we're able to bring and add value to our partners, including operators who want to provide highly accurate services with the complement between power and accuracy for geolocation, for tracking of assets, and provide that service to customers.
A lot to be done still and a lot to prove, I think it's a real milestone for us.
That's very helpful. Just one last one for Emeka. I'll go away. Emeka, you said inventory days obviously will be up in the quarter. Will it still stay within that 90-100 range, or do you think you'll probably go a bit beyond that?
It might go slightly ahead of the 90-100 days. For the most part, we do expect to manage inventory within those levels.
Very good. Thank you.
Next question comes from the line of Harsh Kumar. Line is now open.
Hey, thanks for letting me ask a follow-up. Mohan and Emeka, I was looking at my model. I'm trying to figure out, I know you guys don't guide more than one quarter. I'm going back to your comment about being flattish or possibly even flat to slightly up. At some point in time, I have to build in kind of a hockey stick ramp upward. Do you think that starts to happen with fiscal Q2, or do you think that's mostly a second half phenomenon?
Well, I'll start. Emeka can finish if he wants. I mean, Q2, we're expecting to come back, Harsh, in Q2. Realistically, we've been in the semi space for a long time. When you have one down quarter, you normally find that the second quarter may come back a little bit. It doesn't necessarily come back as a hockey stick. If it comes back, which I do think it will, I think it paves the way for a much stronger second half. We'll see. I don't know how strong the second half is going to be. We have enough growth drivers going on and enough unique things going on in the company that I think that we should be able to outperform.
Thank you.
There are no further questions at this time. Please continue, presenters.
Okay. In closing, fiscal year 2019 was an exciting year for Semtech as we delivered a record financial performance. While we are seeing a very slow start to fiscal year 2020, we believe the strength of the secular drivers behind our growth engines are clearly intact and expect a stronger second half that should contribute to what we expect to be another solid year. With that, we appreciate your continued support of Semtech and look forward to updating you all next quarter. Thank you.
This concludes today's conference call. You may now disconnect.
