Thank you for standing by. At this time, all participants are in a listen-only mode. Later, we will conduct a question-and-answer session. At that time, if you have a question, you will need to press star then one on your push-button phone. I would now like to turn the conference over to Dan O'Neil. Please go ahead, sir.
Good afternoon, and thank you all for joining us today on our first earnings conference call as a public company. Joining me today from Credo are Bill Brennan, our Chief Executive Officer, and Dan Fleming, our Chief Financial Officer. I'd like to remind everyone that certain comments made in this call today may include forward-looking statements regarding expected future financial results, strategies and plans, future operations, the markets in which we operate, and other areas of discussion. These forward-looking statements are subject to risks and uncertainties that are discussed in detail in our documents filed with the SEC. It is not possible for the company's management to predict all risks, nor can the company assess the impact of all factors on its business or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statement.

The company undertakes no obligation to publicly update forward-looking statements for any reason after the date of this call to conform to these statements, to actual results, or to changes in the company's expectations, except as required by law. Also, during this call, we will refer to certain non-GAAP financial measures which we consider to be an important measure of the company's performance. These non-GAAP financial measures are provided in addition to, and not as a substitute for or superior to, financial performance prepared in accordance with the U.S. GAAP.
A discussion of why we use non-GAAP financial measures and reconciliations between our GAAP and non-GAAP financial measures is available in the earnings release we issued today, as well as in our S-1, which both can be accessed using the investor relations portion of our website. With that, I'll now turn the call over to our CEO. Bill?
Thanks, Dan. I want to thank you all for joining our call. Since this is our first earnings call as a public company, I'd like to start with a brief description of what we do. Credo is a pure play, high-speed connectivity company. Our goal is to deliver high-speed solutions to break bandwidth barriers on every wired connection in the data infrastructure market. We've initially targeted the leading edge Ethernet market that's driven by the hyperscaler data centers. We're pursuing an exponential growth curve in speed, and that's driving a large, fast-growing market that, because of its degree of difficulty, is a natural filter on competition. We're building our connectivity solutions to enable these explosive bandwidth increases for every optical and copper connection in the data center.
Market forecasters expect the high end of the Ethernet market to grow at almost 50% per year, and we expect this will create a $5 billion-plus Ethernet TAM for us by 2025. Beyond data centers, we have seen other markets begin to experience exponentially increasing speed demands, and we see that as a great opportunity for us to expand beyond Ethernet. I'll talk a little bit more about that opportunity later. Core to our platform is our SerDes technology. High-speed SerDes is a very high hurdle technology that requires leading edge high-performance analog design and signal processing, and it requires doing it with very low power. We are fortunate to have a team with decades of experience designing to just this type of challenge.
With extraordinary focus on optimizing the mix of analog design and DSP, we can deliver differentiated connectivity solutions with optimized power efficiency and cost effectiveness at the highest speeds. This is why we've been successful engaging with a broad customer base that includes several major hyperscalers, networking OEMs and ODMs, as well as optical module manufacturers. I would like to give a brief overview of our Ethernet connectivity solutions. The first set of Credo solutions I'd like to talk about are Active Electrical Cables, or AECs. We began development more than four years ago, and we've been the pioneer in establishing this new category of connectivity solutions. We targeted our first efforts to enable disaggregated racks in the switching and routing layers in the data center. The traditional way of making these connections has been with passive copper cables known as DACs.
Now, the problem with DACs when you move to 56 Gb single-lane speeds to support either 400 Gb or 200 Gb ports is that the signal integrity becomes a huge challenge. Also, the thickness, weight, and bend radius of the DACs make it very difficult to install and service, especially when you've got installers trying to route more than 200 large cables within a very tight space in the front and the side of the rack. The loss of signal integrity, though, is the real issue with DACs. Now we see the 200 Gb and 400 Gb market as a crossover generation where some companies will commit to the struggle with DACs, but many others will move to AECs due to the signal integrity and form factor advantages.
However, at 112 Gb single-lane speeds to support 800 Gb ports, we firmly believe that DACs are dead. We also have a growing family of AEC solutions that target server racks with connections from the server NIC to the ToR switch. We're delivering highly innovative solutions driven by our hyperscaler partners. For example, in a collaborative effort with Microsoft, we recently introduced the SWITCH AEC, which enables a hitless dual ToR architecture. Our SWITCH AEC is able to detect when a ToR port is failing and then instantly switch the data flow to the redundant ToR switch. This kind of innovation is simply not possible with DACs or Active Optical Cables known as AOCs. Over time, we're going to continue to add other equally innovative NIC to ToR AEC solutions to our portfolio. Next, I'd like to talk about our solutions for optical modules.
The first products we developed are optical DSPs that cover all the optical module deployments today in the hyperscaler data centers, including 100 Gb, 200 Gb, and 400 Gb, and in the future, 800 Gb. In addition to our full family of optical DSPs that we're promoting to the data centers, we're also promoting single-lane 50 Gb optical DSPs for the 5G infrastructure market, as well as 64 Gb single-lane optical DSPs for the Fibre Channel market. Over time, you'll also see Credo expanding our optical solutions in the future, starting with laser drivers. This week at OFC in San Diego, we announced and are demonstrating our first laser driver solutions. Next, I would like to talk about our Line Card PHYs. These are solutions optimized for the copper connections needed by switch Line Card makers for backplane and front panel connections.
We also see emerging high-speed server applications as an opportunity. We're selling our retimers, gearboxes, as well as MACsec devices that provide encryption for applications where security is critical. We've got a complete family of solutions covering the 100 Gb, 200 Gb, and 400 Gb port markets, and this week we announced our products for the 800 Gb and 1.6T port markets. Finally, Credo has SerDes IP license and chiplet solutions, which we've delivered to highly regarded customers across various end markets. While we are primarily a product company, we believe our IP and chiplet solutions are very strategic, enabling us to engage in highly collaborative relationships with industry-leading customers. We count more than 30 customers that have chosen our SerDes IP and chiplet solutions.
When we talk about our competitive advantage, we start with a term called n-1 in reference to the process technology that we're using to deploy our solutions. For any given speed, we can engineer a solution in a more mature process, an n-1 process technology, and that gives us an advantage on development cost as well as our wafer cost. This is where optimizing analog and DSP architectures and doing it all with low power and very small die sizes results in a remarkable value proposition for our customers. This is a true differentiator for Credo. Next, we bring a purpose-built mentality to our solutions. We don't view every link as a one-size-fits-all technology challenge. We engineer solutions that are optimized for the many different links we serve. We've got optimized solutions for optical as well as the many different types of copper links in the data center.
We've got a wide range of SerDes architectures to address the many different links. We have both mixed signal and DSP architectures that are optimized for speed, power, as well as die size. We believe we're the world's leader in mixed signal architectures, and we believe we are the most highly differentiated company for DSP architectures, especially at 112 Gb speeds and beyond. The final source of our competitive advantage is system expertise. We focus on delivering system-level end-to-end signal integrity. We've also developed a tightly coupled firmware base that adds system design flexibility, and we're driving leading-edge system-level test solutions. I point to our AEC family as evidence of the fact that we've gone very far with our system-level mentality. We're delivering a complete system solution versus just an IC solution. All of this boils down to Credo delivering optimized signal integrity, power efficiency, and cost effectiveness.
This is really the key to our success. We feel that our customer engagement is the best validation of our differentiation because when our customers choose to engage with Credo, they're choosing to bet their next generation platform on our execution. Ultimately, it takes a huge amount of trust to make that kind of decision. We're engaged with five of the top seven hyperscalers, and we count more than 20 additional blue-chip clients that include networking OEMs, ODMs, as well as optical transceiver manufacturers and many others. I'm very happy with where we are with customers. Now let's talk about new opportunities that we see within our sights that are beyond the Ethernet market. Other connectivity standards in the data infrastructure market are also experiencing an exponentially increasing demand for higher speed and higher bandwidth.
We're committed to serving the most demanding high-speed markets where we can deliver the same advantages in power efficiency and cost effectiveness. In addition to the Ethernet market, Credo will deliver high-speed connectivity solutions for the USB and PCIe markets. Our solutions are targeting next-generation speeds, so it will be some time before we ramp our products. I'm happy to say that we've signed our first major USB IP license, and that's with an industry leader in the consumer market. Our go-to-market strategy will be similar to our strategy for Ethernet, leading with IP licensing and following with products. We expect these two markets will bring us more opportunity and diversity in our customer base, and we believe this will add roughly $3 billion in TAM in the 2025 timeframe. Of course, none of our goals would be attainable without our tremendous team of employees.
We've scaled our organization very quickly over the past several years, and we now employ well over 350 people globally. This team enabled us to achieve strong results in fiscal third quarter ended January 31, 2022. During this most recent quarter, we achieved approximately $31.8 million in revenue and delivered gross margins at approximately 61%. With that introduction, I'd now like to turn the call over to Dan Fleming, our CFO, to provide more details on our January quarter results.
Thank you, Bill, and good afternoon. I will first review our Q3 fiscal 2022 results and then discuss our outlook for Q4 fiscal 2022. As a reminder, the following financials will be discussed on a non-GAAP basis unless otherwise noted. I'm pleased to share with you that we achieved record revenue of $31.8 million, up 20% sequentially and up 136% year-over-year. This record result was largely driven by strong revenue growth of our products, which also reached a record of $26.7 million for the quarter, up 35% sequentially, and up 190% year-over-year. Our product revenue ramp is at an inflection point as our revenue mix shifts from being IP-focused to product-focused.
This revenue mix shift is first being driven by our AEC products, which continue to ramp at our first hyperscale data center customer. Our largest customer in the quarter was 40% of total revenue, which was associated with this AEC ramp. We expect this customer to remain a large portion of our revenue in the coming quarters as their AEC ramp continues. Our IP business generated $5.1 million of revenue in Q3, up 20% year-over-year. IP will remain a strategic part of our business, but our IP results will vary from quarter to quarter, driven largely by specific deliverables to pre-existing contracts. While the mix of IP and product revenue will fluctuate in any given quarter over time, our revenue mix in Q3 was 16% IP, slightly above our long-term expectation for IP, which is 10%-15% of revenue.
Against the backdrop of a challenging supply chain environment, our team delivered gross margin of 60.7%, up 20 basis points sequentially and up 43 basis points year-over-year. Our IP gross margin generally hovers just below 100%, and our product gross margin was 53.5% in Q3, up 564 basis points sequentially and up 867 basis points year-over-year, based largely on leverage from our strong product growth. Total operating expenses in the third quarter were $18.2 million, up 51% year-over-year as we scaled the organization for growth, but slightly down sequentially as certain R&D project related spending slipped into Q4. We delivered net income of $2.4 million in Q3.
Net income expanded by 20 percentage points sequentially and 41 percentage points year-over-year, a testament to the operating leverage we are driving in the business. Our earnings per share was $0.03 in Q3, up $0.10 year-over-year. Cash flow from operations in the third quarter was $1.7 million, an increase of $7.1 million year-over-year. CapEx was $2.9 million in the quarter, and free cash flow was -$1.2 million, an improvement of $7 million year-over-year. We ended the quarter with cash and equivalents of $240.5 million, an increase of $169.5 million over the second quarter. This increase in cash came from the net proceeds of our successful IPO completed in January.
Our accounts receivable balance declined 25% sequentially to $21.7 million, while days sales outstanding declined to 71 days, down from 101 days in Q2. Our Q3 ending inventory was $26.1 million, up $4.8 million sequentially as we continue our sequential product ramp. Now, turning to our guidance for the fourth quarter, we currently expect revenue in Q4 FY 2022 to be between $37 million and $41 million, up 97% year-over-year at the midpoint. We expect Q4 gross margin to be within a range of 59%-61%. We expect Q4 operating expenses to be between $21 million and $23 million, including the R&D project related spend that slipped from Q3.
Finally, we expect Q4 weighted average diluted share count to be approximately 158 million shares. With that, I'll open it up to questions.
Thank you. At this time, I would like to remind everyone, in order to ask the question, press star, then the number one on your telephone keypad. We'll pause for just a moment to compile the Q&A roster. Our first question comes from the line of Vivek Arya with Bank of America. Your line is open.
Thanks for taking my questions, and congratulations on achieving the IPO milestone during what's such a tough time for the market.
Thank you. Thank you.
Maybe, Bill, a few for you. First on the AEC market, you know, from what we heard at the recent OFC trade show, seems the size and growth of the market could be larger than previously thought. We also heard of some incremental competition from Marvell and maybe others. Maybe give us a perspective of how large AEC is for you today. Where can it go over time, and how do you see this emerging competition?
Yeah, that's a great question. I very much appreciate it. Let me talk about you know what you saw down at OFC in San Diego. Marvell made an announcement that they're entering the AEC market in a big way, and we think this is great. Matt and his team have a strong track record for making good decisions, and we think that he's made another good one. I'll say that you know this is an important you know thing for the AEC market in general. For the past several years, many of our potential competitors have been dismissive of the AEC market opportunity, even going as far as to evangelizing a world that will become exclusively optical.
We see their announcement as a great validation that Marvell and others agree with our long-held belief that AECs really deliver great advantages and will become a de facto solution for short in-rack connections in the future, especially as speeds go beyond 400 Gb. At OFC this week, we're demonstrating our AEC solutions, including the 800 Gb. I'd be honest with you, Marvell's announcement couldn't come at a better time because it drove a huge excitement and interest in our booth. To kind of reflect a bit on, you know, our belief with our approach, and, you know, we've talked about pioneering this product category. We were the first to really invest in a big way.
As a result, we took a really system-level approach. We built a team internally at Credo that focuses exclusively on the AEC system solution. We take responsibility for all aspects, including definition, execution, qualification, quality, and reliability of our solutions. We, you know, are fully standing behind our AECs. We're taking the full responsibility with our customers. We think this approach has been critical to our success thus far, you know, we're intending on increasing our investment over time. Now as far as the size of the market, we've talked about this being, you know, a market in the 2025 timeframe that, you know, is in the $3 billion range, annually.
Now, I think that, you know, as different data centers move towards faster speeds in the switching and routing layer as well as in their server racks, you may see that market increase in size. It's kind of hard to peg it right now. I think that we're comfortably, you know, sitting with 100% market share as we're the first to really come out of the gate in high volume. You know, I think generally we're really focused on the large opportunity that's in front of us during the next couple of years.
Got it. For my follow-up, maybe Dan, one for you on gross margin. How do you see the evolution of gross margins, you know, for the next several quarters as your mix changes perhaps more to the product side? You know, as part of that, if you could just help me clarify the gross margins that you reported, because when I take the $19.565 in non-GAAP COGS and divide it by the sales, I actually get 61.5% gross margin, not 60.7%. Maybe I'm just missing something simple there. If you could clarify that and just give us your perspective on how gross margin evolves this year. Thank you.
Yeah. That's a great. I'm glad you pointed that out, Vivek, because I like your number more than ours. We had because of the way our non-GAAP reporting is done, you might have noticed in the reconciliation there is a warrant contra revenue item. So for non-GAAP purposes, we add back that contra revenue. So when you're calculating gross margin, you need to make sure you add that back to the denominator in your calculation. So that's the difference between the 60.7% and the 61.5%. So while we have this warrant outstanding and there is contra revenue, we'll continue to recognize gross margin on this more conservative approach.
Getting to your broader question, you know, our outlook has not really changed significantly since we last spoke. You know. Let me highlight a few things. From Q1 to Q3 of this year, of fiscal 2022, our product gross margin, if you calculate that, it's actually expanded more than 900 basis points. Nice expansion sequentially each quarter, and that's largely been driven by our increasing scale as we've ramped these new products, especially the AEC product. Now we expect these gross margins to expand, you know, from this point forward in the upcoming years. We don't expect it to be a purely linear expansion. There will be some margin variation from quarter to quarter as we're ramping different products and different customers over the course of time.
If we look in a longer view over the next few years, our product gross margins will continue to expand as we gain scale. Really what that's driven by is, you know, the relatively fixed portion of COGS becomes a smaller percentage of total COGS. In addition, these product mix changes over the upcoming years will continue to drive margin expansion as well. For instance, optical will become a larger revenue contributor in FY 2023 and 2024, where that's just starting to ramp currently in FY 2022.
The last thing I'll mention on margin expansion in our view is, you know, just the market dynamics of the AEC market when we get to 400 Gb AEC cables. We believe that it's a very favorable margin expansion story at that point because of different market dynamics.
Thank you. Our next question comes from the line of Toshiya Hari with Goldman Sachs. Your line is open.
Hi, gentlemen. Good afternoon, and thank you for taking the question, and congrats on the whole process and the strong execution in the quarter. Bill, I wanted to ask you about the supply side of the equation. Obviously very tricky times for everyone out there. During the IPO process, I think, you know, you expressed your confidence in, you know, your ability to secure supply, whether it be wafers or, you know, substrates or what have you. I was hoping to get an update on the outlook there for the next couple of quarters if it feels like things have gotten a little bit more difficult, a little bit more challenging over the past couple of months.
How are you feeling about supply and your ability to address demand for the next, call it 6-12 months? I got a quick follow-up.
Sure. Thank you. And thanks for the question. I love the question because it kind of points out another strength that I believe that we've built as we've built the company over the last several years. We've got a deeply experienced operations team that really has deep relationships within the supply chain. You know, a lot of people, you know, were starting to treat the supply chain strategically when we first started, you know, seeing tightness. We go back to, you know, 2016 timeframe when this team was really forming. We've taken a strategic approach. We've always stayed very close in, you know, in terms of our business plan and our forecasts with our supply chain.
Really about 12-18 months ago, we really formed a much more structured long-term planning approach. I feel very good about where we are. I think that even beyond the next couple of quarters, I see no issues with supporting our very quick ramp. Another thing I'd like to point out is that we've got a deeply experienced customer-facing team. The supply chain challenges have been, you know, something that we've, you know, gone to our customer base with in a sense of bringing a more structured planning approach on that end of it. Believe it or not, I think that the tightness here has drawn us closer to our supply chain as well as drawn us closer to our customer base.
I feel confident at this point that we're not going to see disruptions.
That's great. Thank you. As my follow-up, I had a question on the AEC business as well. In your prepared remarks, you mentioned that, you know, you had a 40% customer in the quarter, and, you know, obviously that customer is doing a lot with you guys in AEC. How should we think about the broadening of your customer base within AEC over the next, you know, couple of years? Again, I suspect this specific customer to be the vast majority of your business in the near term. If you can talk a little bit about sort of the design and activity, and the back and forth you're having with customers specifically in AEC, that would be super helpful. Thank you.
Right. Another good question. Generally, let me say that we're really happy about the AEC ramp with that customer, and it really speaks to the overall growth potential of the overall AEC market opportunity. You know, I think you can kind of look at this, that this is really the nature of being a small, you know, truly disruptive company in a fast-growing market. There's always going to be a first mover as you know, the new innovative product category is brought to market, proven, and ultimately adopted by the first one.
From our perspective, you know, this is really a validation, and it's really unavoidable, you know, that a small company entering a fast-growing market with a limited number of players, you know, we expect it to see a high customer concentration as the revenue scales. We believe really long term that all hyperscalers will use AECs in some form or fashion, whether in the switching and routing layers or in the server racks, especially as single lane speeds increase. The question that you ask is, when are we going to ramp our second big customer? We think that's coming in, you know, the upcoming quarters. I will say that we're deeply engaged with a second hyperscaler, and things have progressed very quickly.
This is again it's more validation. We're also engaged with you know several other customers in you know the whole conversation about AECs. This product category is really quite unique in a sense that we're entering into architectural level discussions with the hyperscalers for their next generation deployments. The answer to your question is I see really within the upcoming quarters we'll ramp our second large customer and then you know over time I see the opportunity expanding you know really more broadly.
That's great. Thank you.
Thank you. Our next question comes from the line of Quinn Bolton with Needham. Your line is open.
Hey, guys. I'll offer my congratulations on the IPO and the first successful quarter post. Bill, I wanted to again follow up on the AEC market. You know, as you walk the floor at OFC, are you seeing any of the AEC competitors looking to develop a SWITCH AEC that could serve as a second source to your product line? Then a follow-up question you mentioned, I think today you're ramping 100 Gb AECs at your first customer. Dan mentioned, you know, as you get to 400 Gb AECs, the margin profile increases dramatically. Can you just give a sense, you know, from a timing perspective, when do you think you start to ship some of the higher speed AECs, especially the 400 Gb and 800 Gb AEC versions?
Yes, I'll make one correction. I think Dan meant to say the 800 Gb is really where we see an opportunity. It's really a shift from single lane speeds being 56 Gb, you know, shifting to 100 Gb single-lane speeds. Please make note of that. I think the way that we view the opportunity is really there's two distinct markets. You know, one market is in the NIC to ToR server racks, and then the other one is with disaggregated chassis or disaggregated switch racks and routers as well. That's really it. You know, we're shipping to customers. These customers are smaller.
They're not, you know, the top seven, but we've had customers, you know, make a very quick decision to, you know, to adopt our technology. We're shipping in production for 400 Gb. But it's not material in a sense of comparing it to our first NIC to ToR customer. It's really a function of, you know, each data center when they, you know, really make the conversion. You know, ultimately it comes down to an architectural decision. I think that what we'll see is during the next, say, 12-18 months, we'll start shipping in a much bigger way for the 400 Gb.
Anything on this, you know, competition-wise to the SWITCH AEC that you provide?
Well, you know, of course, our data center customers, of course, they want multiple sources. This is, you know, part of the rules of the road for them. We've had a couple of competitors try to come up with, you know, the SWITCH AEC that we're shipping in production. I think one of the competitors, you know, hit the end of the road and they're no longer trying to build the solution. I think there's another company that has, you know, possibly delivered samples and, you know, is in the process of trying to get qualified.
Got it. Thank you. Just moving to the Line Card ICs, you guys introduced the Sparrow and Heron retimers and gearboxes this week. Can you just give us a sense, I think at least one of them is currently sampling or maybe already shipping in production, but can you give us a sense of the timing for the revenue ramp on those new solutions?
It's going to be based on, you know, when the 100 Gb single lane switches start shipping. You know, I think generally we're encouraged. Our Line Card business is a very nice business for us. It was the first business that we ramped, and it's very stable and steady. It's not maybe the largest market opportunity, but we think that the trend towards faster single-lane speed on switches will drive growth in the market. I think we're really very well-positioned when that market takes off. It's hard for me to guess, but I would say that it's going to be, you know, maybe more than 6-12 months from now.
Great. Thank you, Bill.
Thank you. Our next question comes from the line of Tore Svanberg with Stifel. Your line is open.
Yes, thank you. This is actually Jeremy calling in for Tore. Question, I guess, on following up on the Sparrow and Heron, and specifically for the retimer, the Heron. Are there any advantages in pairing it with your HiWire AECs, you know, whether on the AEC side or on the Line Card side?
Yeah. That's interesting. I'll also note that some of the 100 Gb per lane switches will go with a 2 RU form factor on the front panel, and they'll use 400 Gb ports. That, you know, that's in an effort to try to get to market quickly, you know, without having to wait for 800 Gb solutions to be available. The Heron part, there's a gearbox mode where it can receive 100 Gb lanes from the switch, and then it can, you know, speed shift to 50 Gb lanes for the 400 Gb modules. Naturally, if you're using a combination of products, there's going to be, you know, extremely straightforward interop. But again, the whole industry is building towards this, towards an IEEE standard.
You know, I wouldn't expect that there's a huge advantage. We're not building in secret features if you know, we're following the standards. I would expect that it would be very straightforward, maybe more straightforward than connecting with another solution. No huge advantage.
Got it. As we look to, you know, opportunities beyond Ethernet, you mentioned USB and PCIe, and with the, you know, the first customer on the consumer side, can you tell us, you know, for USB, can you tell us what kind of applications specifically, you know, you see ramping first and then, you know, over time, what's the balance between USB and PCIe in terms of the TAM? Thank you.
A good question. I think that, you know, the folks that follow the standards in the USB space know that there's, you know, typically a doubling of speed every generation. You know, we expect that laptops, tablets will be the first application that adopt the fastest speeds. We expect that, you know, the peripherals that you plug in to laptops or tablets will need to go to that same speed to really take advantage for the applications that wanna take advantage of the bandwidth.
I think there's a large market in cabling as well because of that speed. There is a necessity to have some sort of active solution for cables that are over, you know, even 2 ft or less. We expect those will be the first markets to ramp, and I think there are other applications that will drive high bandwidth that will follow.
Great. TAM expectations in terms of USB versus PCIe?
We see that USB has the larger potential. I would probably break it down to maybe, you know, 60%-65% of that number that I said would be TAM driven by USB, and then the balance would be for PCIe.
Great. Thank you very much, and congrats on a great quarter.
Thank you. Thank you.
Thank you. Our next question comes from the line of Vijay Rakesh with Mizuho. Your line is open.
Yeah. Hi, Bill and Dan. I'll add my congratulations on a solid IPO and a good first quarter here.
Thank you.
Just on your visibility, I was wondering, your peers have talked about very strong visibility into first half. Just wondering how you, how your visibility was. If you know how the backlog looked like as well. I have a follow-up.
Yeah. Just to make sure that we understood your question, you're asking about our visibility in the first half, as well as-
Yeah. How did as you look out.
As I mentioned before, you know, part of the process that we've gone through with our customers due to the supply chain challenges is to really, you know, get as far a look possible at what their demand profile will be. I would say that we've got good visibility right now. You know, we're on a very regular basis trying to refresh that visibility with our customer base. It is critical to make sure that we've got products that we can supply. I think that, you know, our visibility is probably better now than it was prior to the kind of supply chain tightness.
Got it. Going back on the Marvell question, I know they are doing this, probably with Amphenol, but I think where you differentiate is you have a much more integrated cable that goes in sync with your SerDes steps and, you know, obviously a much broader portfolio with speed and phase shift and DL-TOL, as you have noted before. It also took you 2+ years to, you know, kind of get this out in the field and qualified, right? Is that, shouldn't that be a pretty significant proprietary moat for you going forward? That's it.
Yeah. It's a very good question. You know, I can speak to our approach. I don't feel great about speaking towards a competitor's approach and you know, playing that game. What we found as we were in development on these AEC solutions is that it was not straightforward to hand off our device to a partner and expect the partner to take it forward, even if I provide the firmware as a starting point. That's why we quickly decided to assemble our own team internally that took ownership of every aspect of the design all the way through qualification. We defined, you know, the tests, the equipment that's used to test our cables. We wrote all the firmware for the test.
We wrote all the firmware on the cable side. You know, we optimize every single pair of wires for signal integrity as part of our manufacturing process, but we're defining every step. We felt like taking the full responsibility and really standing behind it with our customer base was the right approach, very similar to our IC solutions. You know, it's the single throat to choke mentality. If something happens to go wrong, you can't, you know, be pointing at each other saying, "It's not my problem." This is our approach, and you know, we feel like it was critical for our success. It's not to say that others couldn't overcome the hurdles of you know, trying to divide the work and divide the responsibility.
Got it. Thanks.
Thank you. As a reminder, ladies and gentlemen, that's star one to ask the question. Our next question comes from the line of Suji Desilva with Roth Capital. Your line is open. Check to see if your line is on mute.
Hey guys, sorry about that. Hi, Bill. Hi, Dan. The initial customer that's ramping up here, can you talk about whether there's an initial ramp volume or whether it should be steady going forward, Dan, in terms of this lead customer that's kicked in initially?
Yeah. Unfortunately, we can't really talk about specifics about customer engagements like that at that level of detail.
Yeah. I would probably add that we're, you know, we're in the early stages of the ramp. We expect it to, you know, continue to ramp throughout the calendar year. You know, it's really a function of their own plan and, you know, and that's. You know, ultimately, you know, we're trying to stay as close as possible, and we're getting forecasts that, you know, throughout in time even to the order of 12 months. I think, you know, it's something you'll see continuing to ramp.
Okay. Thank you. That color helps. Just for the other customers that are coming, following on, can you remind us the length of the qualification cycle on average, and is that what is going round right now, or is it more driven by the customers transitioning to various platforms that would bring you in? Any distinction there would be helpful.
Sure. It's very interesting. You know, if we look at some of the cables that we're targeting for the switching and routing layers, these are, you know, 400 Gb or 200 Gb solutions. You know, it's really great because when a customer decides to qualify the cables, you know, it is a very straightforward thing. We ship them, you know, enough cables to build a rack. You know, they assemble the rack, they qualify the solution, and they can begin production really quickly. From start to production could be as short as 6 months because this is a fully baked solution. When we're looking at a Line Card design, you know, you get involved in the first stages of a big switch maker laying out their PCB.
You know, sometimes it takes on the order of 18+ months to go from you know first effort to production. It's really nice, the work on the AEC because it is a system solution that's done before, and it can be very quickly qualified. You know the first ramp that we've had, this was really a collaborative effort. This was one where you know kind of core to our values are you know the concept of listening to customers, helping them solve problems, and making them successful. This was an opportunity where we earned enough credibility for our customer to approach us and say, "Do you think this is possible?" You know from start to production was on the order of 18 months in that case.
You know, but again, this is, you know, this is evidence of the fact that there's real innovation opportunities that have never been seen before because nobody's really taken approach to make an active solution like we have. I will say that the second effort that we've got underway, the second engagement, it's a similar type of engagement where they're not picking up a standard cable that we've developed. It's something that's again, you know, an idea that you know comes from listening to our customers and helping them solve their problems. That one's not going to ramp so quickly, but you know I would say in the upcoming quarters, we'll see the initial ramp.
Okay. Thanks, guys.
Thank you. Our next question comes from the line of Richard Shannon with Craig-Hallum. Your line is open.
Hi, guys. Thanks for taking my questions, and congratulations on the first quarter out of the gate here. Maybe I'll just ask a quick tackle question for Dan on the guidance here. I think you're suggesting from your prepared remarks that the cables be the kind of a big sequential driver here. So just wanna check to see if that conclusion is right and if you're expecting IC growth, product IC growth to also grow. Then just kind of as a corollary to that, you talked about a 40% customer in the last quarter. Is it safe to think of this concentration being at least as that high in the April quarter as well?
Yeah, those are all steep questions. The last question, yes, we would expect in Q4 a similar type of concentration from customers since they're going through that ramp right now. As far as what's driving growth in Q4 in our guidance, it really is. You're correct in your assessment. It really is AEC. We expect our IP revenue to be relatively healthy as well. You know, generally speaking, yes, you're accurate. You're correct.
Okay. Thanks for that, Dan. Bill, a question for you, since I haven't heard a question here on your optical ramps here. Just wanna get your latest update, especially as your team goes through OFC on your thought process and on timing, of when you're expecting to see a real ramp up in production volumes on the optical DSP side.
Sure. Yeah, it's been a big week for us at OFC. Got a large team down in San Diego. We feel like we're in great position on our optical products. You know, and this is a product development that is a little bit longer in nature to get to production because we've got to get through qualification with our customers, and they've got to get through qualifications with the hyperscalers. I'm happy to say that we've started production shipments to several customers. Not a material amount of revenue yet. It's small, but we do expect that the large number of design engagements that are ramping in the upcoming quarters will generate material revenue in our fiscal year 2023. You know, it's also interesting.
We've got solutions that cover the 50 Gb per lambda market as well as the 100 Gb per lambda market. You know, going back, you know, 5 or 6 years, or so, I was new to the market and, you know, the market was basically, you know, the forecasters were saying that, 100 Gb per lambda is coming, and that's the only market that you should target. Ultimately, we made the decision to invest in 50 Gb per lambda. Although many industry watchers believe that the 50 Gb per lambda market was cast in stone, we're now playing the role of disruptor. We've got multiple engagements, including 200 Gb, 400 Gb, single lane 50 for 5G and also 64 Gb for Fibre Channel.
It shows that although it's important to be on the leading edge, there's still great opportunity in existing markets. I think everybody's aware that, you know, three major data centers are going with a 200 Gb module approach for their ramping next-generation architecture. We also have several design engagements for 100 Gb per lambda, including both 100 and 400 Gb. Down at OFC this week, we're demonstrating a broad set of our solutions, including 200 Gb, 400 Gb, 800 Gb, as well as the single lane products I described. I'll note that, you know, our module partners played a big role in helping us with demonstrations. II-VI, Accelink, CIG, Hisense, Luxshare, and O-Net all provided Credo-based modules that are being demonstrated this week.
I think, you know, more on it. I think key to this market is driving best performance with best power efficiency and doing it, you know, with the best possible cost. It can make or break customers in this market depending on how cost-effective your solution is. We are demonstrating 800 Gb at OFC. I'll say that, you know, we're probably never going to win the competition on press releases. We're just a little bit more conservative in our approach. I'm really confident that we'll have equal or better performance and power, but for sure we're going to deliver the most cost-effective solution. That's really, you know, based on our N-1 process approach.
Okay, perfect. That is all from me, guys. Thank you.
Sure.
Thank you. I'm showing no further questions in the queue. I would now like to turn the call back over to Bill for closing remarks.
Yes, thank you, everybody, for actively participating in our first earnings call. We very much appreciate your ongoing interest in Credo. With that, I'll say take care until the next time we talk.
Ladies and gentlemen, this concludes today's conference call. Thank you for your participation. You may now disconnect.
