Thank you, Sandy. Good afternoon, everyone. For Q4 fiscal 2019, net sales were $160,000,000, an 8% sequential decline and an increase of 14% from the same period a year ago. Fiscal year 2019 net sales were a record 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 PO was coming from the industrial and communications end markets. Q4 bookings softened Q over and resulted in a book to bill below 1. Advanced bookings accounted for approximately 45% of shipments during the quarter.
Q44 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 nonrecurrence of the one time benefit from reduction in deferred value of contingent earn out obligations in Q3. In Q4, GAAP interest on expense was $548,000 and benefited from a $1,300,000 gain on the sale of an investment. Compared to $31,200,000 of expense in Q3, which included the $30,000,000 in payment of our modified investments. Q4 GAAP tax rate was approximately 49 percent, driven by a discrete item related to acquisition related intangibles.
The excess tax benefits of Comcast exercising is remaining warrants. We'll drive our Q1 GAAP tax rate to a benefit in the range of 8% to 12%. We expect our GAAP to 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 nonrecurring 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 closure of the impact of the Comcast warrant on the financial statements in our Form 8 K filing and our press release. Q44 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 higher 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 $53,100,000, down 2% from Q3, driven by lower variable compensation expenses. In Q1, we expect non GAAP operating expense to decline between 2% to 6% sequentially as a result of lower variable compensation expenses, driven by lower revenue. We expect our non GAAP operating expenses 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% 19%. In Q4, cash flow from operations increased 22 percent over the same period a year ago to $47,000,000 or 29 percent of net sales.
For fiscal year 2019, cash flow from operations increased 65% over fiscal year 2018, to $184,000,000 or 29 percent of net sales and represented a new record. Free cash flow was 27 percent of net sales for both Q4 and fiscal year 2019 and in line with our upwardly revised a target range of 25 percent to 30 percent. In Q4, our cash and investments was flat at $312,000,000 and our debt balance was approximately $212,000,000, resulting in a net cash position of $100,000,000. We repurchased approximately 771,000 shares of $36,500,000 of stock in Q4. And $2,400,000 or $116,200,000 in fiscal year 2019.
And our stock repurchase authorization now stands at approximately $181,000,000. 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 or 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 2019. Our net sales grew 7% year over year to a new record while our 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 and we repurchased 2,400,000 shares or 3.7 percent of our issued and our outstanding stock in fiscal year 2019.
While the geopolitical macro issues echoed by our peers is contributing to near term headwinds on the 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 twenty twenty.
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 and 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 $160,000,000. 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 percent 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 percent 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, and approximately 8% was attributable to other consumer systems. The industrial and communications end markets also declined over the prior quarter and represented 32% 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 Product Group increased 2% over the prior quarter and 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 Clear Edge 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. And initial customer feedback is very positive in applications, which require the highest performer 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 100 gig, 200 gig and 400 gig optical modules and also sampling and receiving positive customer feedback. Our fiber Edge 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 100 gig ClearEdge NRZ platforms 200 gig and 400 gig PAM4 optical modules using our fiber edge 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 1 gig, 2.5 gig and emerging 10 gig PON module market.
We recently introduced several new PON platforms leveraging our fiber edge PMD technology that we believe will enable us to extend our leadership position over the next few years as the market transitions to 10 gig 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 backhaul links and 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 seeing 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 10 gig 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 over the prior quarter and represented 26 percent 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. And 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 investments 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 2492 SQ. 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, but 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 Birds chose business orange business services to connect Veolia's 3,000,000 intelligent water meters in France over the next 10 years using the Orange LoRa network. SEMTech's 126X LoRa transceiver platform was named the Analog Semiconductor of the Year at the Electro Awards. And 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 2300 and 3 new design wins. Now 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 demand strong momentum from our pre business units. We also achieved 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 9317 new design wins.
In FY 2019, our Signal Integrity Product Group achieved record net revenues, driven by record CDR, record pawn 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 FY2019, our Protection Product Group grew 3% to deliver a solid annual performance as we continue to successfully diversify into new verticals. In FY19, Semtech's LoRa business achieved record results with LoRa enabled revenue increasing over 85% from FY 2018 to approximately $78,000,000. In FY 2019, we were pleased to exceed nearly all the metrics we targeted the beginning of the year.
These metrics included the number of public or private LoRaWAN network operators, 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 FY20. 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 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 1.2000000000 connected end nodes. We expect the number of LoRa gateways deployed to double in FY20 to over 500,000 enabling a lower end node capacity of over 2,000,000,000 end nodes. The cumulative number of lower end nodes increased to $87,000,000 at the end of FY 2019 from $50,000,000 at the end of FY 2018. We expect this number to continue to grow rapidly and exceed $114,000,000 cumulative end nodes by the end of FY 2020.
The LoRa Opportunity pipeline exceeded $400,000,000 at the end of FY 2019 with an additional $200,000,000 of leads feeding the pipeline. We anticipate that on average 40% to 50% of this pipeline will convert to full deployment over a 24 month timeline. In addition, while historically some 50 percent 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 extremely soft demand from China, we still expect our LoRa enabled revenues to be between $100,000,000 $140,000,000.
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 machine Q 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. And Tata announced that together with Genesis Gas Solutions, they have won a contract with IGL in India, to deploy prepaid smart gas meters using Tata's LoRaWAN network.
We expect Tata to win many more Smart Metering contracts across India. While still in its early stages, Tata's LoRaWAN network is expected to eventually cover over four hundred million people in India. In the future, we expect to see 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 microservices to grow to between $80,000,000 $100,000,000 in revenues within the next 5 years. Along with the LoRa Alliance, we expect to continue to drive LoRa to become the defector standard for global LP WAN use cases, in what we expect to be a multibillion unit industry in the next 5 years. Now let me discuss our outlook for the first quarter of 2020.
Despite a marked improvement in our bookings in the last 2 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 $125,000,000 and $135,000,000. To attain the midpoint of our guidance range or approximately $130,000,000, we needed net terms orders of approximately 40% at share. I will now hand the call
We have your first question comes from the line of Torese Vanberg from Citi. Your line is now open.
Yes, thank you. And 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? And 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 refers to is related to data center. But I would say it's broad based. It's across all markets, all businesses, all regions.
Very good. And could you also update us on the Alora pipeline, what you're expecting for maybe fiscal 2020? Obviously, it stood at 4 100 plus, in fiscal 2019. Do you have a number for fiscal 2020?
Yes, I expect it to end at $600,000,000 in opportunity. The $200,000,000 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. So I would say by the end of FY 'twenty, we'll be somewhere between $700,000,000 $700,000,000 in opportunity.
Your next question comes from the line of Craig Ellis from B. Riley. Your line is 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 as you got 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.
And 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.
So the data center business, our customers tell us by mid to end of Q2, they expect to start, the orders to start picking up again. They do see inventory there. But they expect that to come back. And we know that there's still pretty big ambitions in terms of hyperscale data center build out across the globe. So we do expect that to be a predominantly a first half issue.
Obviously, the trade issues give us a lot of concern because of 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. And so just a lot of angst and about placing orders and, and, things like that. So any resolution for sure will just free up, clear up the uncertainty and and help customers take more risk, I think, which is important at this timeline.
Okay, that's helpful. And if I could just ask a follow-up You guys talked about shifting mix shift, a positive mix shift for your 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 kind of margins moving throughout the year even as have maybe a bit of a disappointing first quarter?
So, 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 protection in industrial and automotive design wins. So clearly, we do see a lot of the revenue growth going forward coming from the higher gross margin end markets like industrial.
And that is why we do believe that we should expect to see our gross margins stable, but also finishing 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 Jaffray. Your line is now open.
Yeah, hey, guys. Thanks for letting me ask a question. Mohan, I had a simple question. If I was to take the 1 $60,000,000 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? And then also you mentioned that business teams have stabilized actually looking up very, very nicely in the last 2 weeks, in terms of ramp continuing through the rest of the year?
How do you see the rest of the year? And previously, I think you guys have made a statement that fiscal 2020 could be flattish possibly being up, does that even does that still hold true? And then I've got a follow-up.
Well, 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, but it depends a lot on the second half. The way we look at the year currently as Q1 obviously is very soft. Q2 will start to improve.
And then we are expecting a stronger second half, obviously. And then 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. 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. So that has an impact on all of our businesses. Frankly, wireless our LoRa business is a significant business in China, China handsets also and then also related to our SIP business. So we do expect, as that starts to get better, if China improves, obviously that will be a positive for us. But that's the those are the main drivers of the weakness in Q1.
Fair enough. And for my follow-up, Mohan, I wanted to ask about Laura. I think you mentioned $100,000,000 $240,000,000 for this year. Which is a little bit off from your previous estimates. Now given that they were put out 3 or 4 years ago, we get that Is that predominantly a function of what's going on in China and what you're seeing here?
And also as your additional $200,000,000 of leads, does that include tags or microservices in it or is that just pure chips?
Yes. So the leads and opportunities are all related to chips. Including tags, tags are chip related products. So but not microservices. That's a different goes in a different bucket for us.
And then coming back to the range, it does it is really significantly impacted by China softness. I mean, we We have been seeing a deterioration, I guess, midway through Q4 in our China business overall. And as I mentioned, the POS has come down significantly. So that has changed things. And that's one of the reasons I mentioned that the opportunity pipeline 70% of that is outside of China.
So the lower up, balance I think from a regional standpoint is going to shift nicely. But that's going to take a little bit of time. Now bear in mind, the $100,000,000 to $140,000,000 in FY 2020, if we achieve the midpoint of that range, would still be up more it would be up 56% or 54% something in that range, which is, significant in the market environment we're in. So And as things improve through the year, I'll obviously keep you updated.
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. So 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 conversations, 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 in the trade side yet?
Yes, that's a good question, Mitch. I think the China, we have to break it out into where we have business in China and that 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 is really the China demand situation is kind of the biggest piece of it at the moment.
And we do expect that 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. And so we don't see a change there. Data center is the same. Our customers are still telling talking about deploying lots of larger scale data centers, but there is inventory at the moment. So those give us indication that the second half probably going to be stronger.
How much stronger is a good big question? Then if I look at the other businesses, smartphone, for example, we're starting to see a little bit more, positive kind of, trends there. And as I mentioned, the bookings over the last 2 weeks of strengthened. So that kind of supports some of that. And then Laura 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. Yes, just to follow-up there. So I think the lower one makes sense essentially just the timing of what quarter comes in. When I look at the 2 kind of bigger debate points in the semi space within smartphones or data center. So of those 2 within your guidance of talking about, call it, flattish 2020, which one are you guys more comfortable with in terms of growth, the smartphone side or the data center side?
Yes, I would say it's more based on what happened in 19 and smartphones was, not so strong in FY19. I think that there's a good chance it will be stronger, particularly if China and North America do better. But the smartphone business, as you know, is, can be tricky. Now one of the things 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 of Q2, we'll start to see that pickup. But 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 And 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% to 50% China based and the but international or non China was 70% of the design pipeline. Just want to make sure I got those numbers right.
Yes. In FY 2019, that's our last fiscal year, Quinn, about 50% of the revenues is approximation, but about 50% of the revenues was driven out of China. The opportunity pipeline as we look at it, 70% of that is outside driven by outside of China. Large part of that is North America, but other regions outside China also. And so as we see that 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, I'll make a point of that is because China is very weak at the moment.
And then a follow-up, Mohan, on the on Laura, you gave us some very specific guidance for the number of network the number of countries greater than 500,000 gateways, greater than $140,000,000 cumulative end nodes, but the revenue range of 100 to $140,000,000 is fairly wide. If you hit those metrics on networks, countries, gateways and nodes, does that kind of put you towards the middle of the 100 to 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 puts you at the midpoint of the range or better or worse?
Yes, I would say it's better, Quintin, 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. So I would say that cumulative end nodes though, if we hit $140,000,000, I think it will, take us closer to the high end than the midpoint.
Perfect. And then 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 other products in the optical space?
Well, just really a clarity around our strategy and confirmation that I think 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. And then as we look forward, I think the consistent theme is high performance, but at the lowest power and the lowest cost and we're having a Tri Edge family out there now being able to talk to customers as we're sampling, for both two 100 gig modules, short reach modules, eventually longer reach modules, and then eventually, combined with other platforms to provide really a roadmap for our customers, I think, is very good for the PAM4 plans. And then the fibroids 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. Plus then 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 And then 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. So 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 color, Mohan.
Your next question comes from the line of Doree 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 second half. How much I know it's hard to quantify, but how much of that is kind of the market coming back versus some of these new new programs.
And I'm thinking especially the, the PAM4 CDRs for, for 20400 because my sense is that's probably more of a fiscal 2021 event, but just want to understand sort of, is that correct? How much is going to be market?
Yes, that's correct already. Most of the PAM4 stuff is going to be later part of this year and into next year. So it's all market driven. It's all inventories being used up and some of the hyperscale stuff continuing to build, to build out it's a pretty global statement, I think, on data centers. I think we've seen China started to pick up.
But again, with the China softness, that's, has muted. But I do think it's more driven by market dynamics. I don't think it's specific to PAM4.
Okay, very good. And 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. So 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 Laura?
Yes, I think, and I alluded to some of those on my prepared remarks, but Orange is when, with Veolia, is a significant milestone for an operator, very significant, actually, over a 10 year period. So that's one. And then if I I made some comments on some new use cases, Comcast, with machine queues, Victor, rat trap or rodent trap connectivity, that one is a very interesting use case that I think has as 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. And Tata is another one where winning a gas metering, LoRaWAN use case in India, it kind of pays the way for them to then when many more, similar types of, use case wins or whether it's gas metering or water metering or whatever, And that's great for the operators.
The operators that have joined the LoRa Alliance and have built out LoRaWAN Networks have obviously taken risks. They built out the network or put their name behind it and are now looking for use cases and and real demand. And so that's, 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 for many 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.
So, a lot to be done still and lots to prove, but I think it's a real milestone for us.
That's very helpful. Just one last one for Emeka, then I'll go away. So Emeka, you said inventory days obviously will be up in the quarter. Will it still stay within that $98,000,000 to $100,000,000 range? Or do you think you'll probably get go a bit beyond that?
It might go slightly ahead of the 90 to 100 days, but 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. Your line is now open.
Yeah,
hey, thanks for letting me ask a follow-up. Man and Emeka, looking at my model and I'm trying to figure out, I know you guys don't guide more than 1 quarter. But I'm going back to comment about being flattish or possibly even flat to slightly up. So at some point in time, to building kind of a hockey stick ramp upward. Do you think that starts to happen with fiscal 2Q, or do you think that's mostly a second half phenomena?
Well, I'll start and then Emeka can finish out if you want. So I mean, Q2, we're expecting to come back harsh in Q2, but 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, but it doesn't necessarily come back as a hockey stick. But if it comes back, which I do think it will, then I think it paves the way for a much stronger second half. So we'll see.
I don't know how strong second half is going to be, but 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.
There are no further questions at this time. Please continue presenters.
Okay. In closing, fiscal year 2019 was an exciting year for Centec 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.
This concludes today's conference call. You may now disconnect.
