Credo samples low-power optical DSPs with integrated DML drivers

Credo introduced two high-performance, low-power optical DSPs that come with the integrated directly modulated laser (DML) drivers critical to supporting high-density data center design and optical transport networks.

• The Seagull 52 can be used as a bitmux or retimer in next generation QSFP28, DSFP, SFP-DD and SFP56 optical transceivers. In bitmux mode, the DSP is configured with two lanes of 25Gbps NRZ on the host side to one 53.125Gbps (26.5625GBd) PAM-4 lane on the line side. In retimer mode, Seagull 52 is configured as one lane of 53.125Gbps PAM-4 to one lane of 53.125Gbps PAM-4. Legacy data rates are supported for backwards compatibility. Seagull 52 supports industrial temperatures of -40°C to +85°C and can be used in 5G wireless front, mid, and back haul, and high-density data centers.
• The Seagull 202 DSP is a full duplex product that can be used in next generation 4x50Gbps QSFP28 optical transceivers for high density data centers.

Both products include a high-performance DSP engine. The DSP engine enables uncooled direct modulated lasers (DML) to be used in applications requiring industrial temperature, due to the increased non-linearities and signal impairments associated with the channel and optics of the engine. The DSP engine also enables use over an extended range of wavelengths in wavelength division multiplying (WDM) applications. The optical line side transmitters include integrated DML drivers with programmable laser currents to simplify module design. A number of test and debug features enable rapid bring-up, simplified lab and production testing, and reduced time to market.

Sampling is underway.

“The continued global roll out of hyperscale data centers and 5G networks requires more fiber, more towers and more bandwidth with a view to minimizing power,” said Scott Feller, Vice President of Marketing at Credo. “These new additions to Credo’s Seagull product line will allow our hyperscaler and telecom customers to meet relentless capacity demands thanks to the reach distances supported, design flexibility enabled, and industry leading low power dissipation provided.”

Ostrich is a multi-protocol high-speed SerDes supporting data rates up to 25.6Gbps NRZ and 40Gbps PAM3. A single bi-directional lane supports channel insertion loss up to 30dB bump-to-bump at 40Gbps with spread-spectrum clocking (SSC) enabled while achieving very low power to address all key application use cases. Credo's unique SerDes technology enables silicon solution providers and OEMs to manufacture custom chip solutions which address new market opportunities, while delivering on critical performance and low- power system level requirements.

Credo says unique mixed signal approach was first applied with the move from NRZ to PAM modulation when Ethernet connectivity jumped from 25G to 50G. With new applications demanding two times the throughput, and current single-lane data rates maxing out in the 20G to 32G NRZ performance range, the move to advanced modulation schemes enables higher performance at the lowest possible power. To enable 40Gbps performance the company determined that PAM3 offered the best overall balance of performance and power.

Bill Brennan, Credo’s President and Chief Executive Officer stated: “The data infrastructure market is experiencing an exponential increase in bandwidth demand. There is a revolution happening as new markets and standards, including those for applications such as consumer devices, small-to-medium sized business, automotive and others demand higher-speed connectivity at lower power. Credo is addressing the expansion of the connectivity ecosystem by delivering industry-leading performance with advanced IP solutions like our Ostrich 40G PAM3 SerDes, while in parallel providing complementary IC product solutions."

Credo pushes LP SWITCH Active Electrical Cable to 200G

Credo announced the 200G HiWire LP SWITCH Active Electrical Cable (AEC) for connecting servers to to two Top-of-Rack (TOR) switches for hitless failover. The solution architecture was jointly announced in July 2021 by Credo and Microsoft, whose SONIC Dual TOR Management Container controls the SWITCH AEC.

The HiWire LP SWITCH AEC 200 has QSFP56 (Quad Small Form Factor Pluggable) connectors with integrated Credo PCS termination. The cables support 50G, 100G, and 200G with optional speed-shifting between 56G PAM4 and 28G NRZ lanes on both the NIC and TOR ends. The new 200G AECs join Credo’s diverse HiWire family for 100G, 200G, 400G, and 800G systems.

“Thanks to Credo’s advanced purpose-built SerDes architecture, our 200G LP SWITCH AEC has doubled its speed in the last six months while staying inside the same power envelope.”

Data processing and storage power can be monetized but not the power consumed for data transport. Credo’s low-power LP SWITCH AECs help minimize data transport power and enable data center architectures that eliminate redundant failover server racks.

“Power is the most important and most difficult parameter to control in hyperscale networking,” said Don Barnetson, Vice President of Product, AECs at Credo. “Thanks to Credo’s advanced purpose-built SerDes architecture, our 200G LP SWITCH AEC has doubled its speed in the last six months while staying inside the same power envelope.”

“As NIC speeds increase rapidly in the hyperscale datacenter, reliability must not be compromised,” said Lihua Yuan, Partner Development Manager at Microsoft. “Credo’s 50G and 100G HiWire LP SWITCH AECs are already proven and up-streamed in SONiC with the 200G LP SWITCH AEC creating a path for next-generation NIC speeds in 2022.”

“Emerging trends such as AI and 5G are driving exponential growth in the performance demands of the modern data center,” said David Iles, Senior Director of Ethernet Switches at NVIDIA. “The NVIDIA Networking platform equips innovators as Credo with the network bandwidth and low latency required to supercharge the modern data center with breakthroughs such as the HiWire LP SWITCH AECs.”

"Reliability is more critical for telecommunication service providers than for hyperscalers," said Keyur Patel, Founder and CTO, Arrcus. “Credo’s HiWire LP SWITCH AECs provide 5x9s (99.999%) rack reliability and enable us to ensure autonomous high availability (HA) from the Arrcus Connected Edge (ACE) platform with a sub-microsecond failover."

Credo announces 800G HiWire Active Electrical Cables

Credo announced its new 800G HiWire LP CLOS Active Electrical Cable (AEC) for distributed, disaggregated chassis (DDCs) used in hyperscale infrastructure. 

The new 8 x 112G per lane copper cable interconnect is the first member of Credo’s 800G AEC family.

At just 32AWG, 800G AECs are about as thick as standard Cat6e cabling. This narrower gauge reduces cabling volume by up to 75% versus passive copper DACs. LP CLOS AECs are available in lengths up to 2.5m. Credo’s new AECs consume half as much power as optical cabling solutions and feature superior reliability with up to 100 million hours of Mean Time Between Failure (MTBF).

The LP CLOS AEC 800 PAM4 cables come in QSFP-DD800 (Quad Small Form Factor Pluggable Multi-Source Agreement Group) and OSFP (Octal Small Form Factor Pluggable) types. Integrated Credo retimers enable the cable to achieve high performance without needing additional external components, simplifying the design and lowering system cost and power. The new 800G AECs are identified by their distinctive HiWire purple color sheath. 

Credo is sampling the LP CLOS AEC 800 now with general availability expected in early 2022.

Credo says that  at 400G and higher, AECs offer greater signal integrity and break through the physical weight, bend radius, and range limits of passive copper Direct Attached Cables (DACs). 

“Credo sees 800G as the point where passive DACs hit the wall – they are far too thick and rigid for many customer applications and impose a high cost and engineering burden on switch manufacturers,” said Don Barnetson, Vice President of Product at Credo. “Credo’s new 800G LP CLOS AECs route like Cat6 cables and offer up to 100 times better reliability and half the power of optical cabling solutions. The future of connectivity is clearly purple.”

 Credo introduced its Seagull 200 Optical DSP for supporting high-performance QSFP56 optical modules to enable 200GbE SR4, DR4, FR4, and LR4 applications in hyperscale data centers, cloud networks, and 5G wireless mid-haul and back-haul networks.

Seagull 200 accepts four lanes of 53.125Gbps (26.5625Gbaud) PAM4 on the client (host) interface and sends the traffic to four lanes of 53.125Gbps PAM4 signal on the optical (line) interface. The device is designed in Credo’s unique architecture and optimized for die size and mainstream silicon process technology, enabling low cost-of-ownership and accelerating 200GbE market adoption.

Seagull 200 (CFD50502) integrates high-performance digital signal processing (DSP) engine and equalization techniques to compensate for optical impairments while achieving good BER performance and maintaininglow power dissipation. The architecture has minimal and deterministic latency that is needed in the mobile infrastructure. 

Seagull 200 comes with advanced diagnostics and loopback features to reduce time-to-market and aid with rapid system debug. The device footprint is compatible with Credo’s low power Dove 200 Optical DSP, which allows customers to design a common PCB for either component and choose the DSP that best meets the application need.

“Seagull 200 is the ideal high-performance and low power DSP for data centers and for 5G wireless mid-haul and back-haul deploying PAM4 networks,” said Scott Feller, Vice President of Marketing at Credo. “The low power and fixed latency enable 200G upgrades on the next generation wireless networks,” Feller added.
