Credo targets hyperscale data centers and 5G networks with new optical DSPs


New Seagull DSPs deliver high performance and low power consumption with Integrated DML Drivers

SAN JOSE, Calif. — September 14, 2022 — Credo Technology Group Holding Ltd (NASDAQ:CRDO) today introduced two high-performance, low-power optical DSP ICs; the single-channel Seagull 52 and the four-channel Seagull 202. Credo designed these new Seagull DSPs to meet the demands of the most demanding hyperscale and 5G applications by delivering higher bandwidths and low latency variation combined with ultra-low power dissipation. Both devices come with the built-in Direct Modulated Laser (DML) drivers essential to support the design of high-density data centers and optical transport networks.

“The continued global deployment of hyperscale data centers and 5G networks requires more fiber, more towers and more bandwidth to minimize power,” said Scott Feller, vice president of marketing at Credo. “These new additions to Credo’s Seagull product line will enable our hyperscalers and telecom customers to meet relentless capacity demands with supported reach distances, enabled design flexibility, and low power dissipation at the industry leading provided.”

Both products include a high performance DSP engine. The DSP engine allows the use of uncooled Direct Modulated Lasers (DMLs) in applications requiring industrial temperature, due to the increased nonlinearities and signal degradations associated with the channel and engine optics. The DSP engine also enables use over a wide range of wavelengths in wavelength division multiplication (WDM) applications. Line-side optical transmitters include built-in DML drivers with programmable laser currents to simplify module design. A number of testing and debugging features enable fast commissioning, simplified lab and production testing, and reduced time to market.

About the Seagull 52:

The Seagull 52 is a versatile product that 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 25 Gbit/s NRZ lanes on the host side to a 53.125 Gbit/s (26.5625 Gb) PAM-4 lane on the line side. In resynchronization mode, Seagull 52 is configured as a 53.125 Gbps PAM-4 lane to a 53.125 Gbps PAM-4 lane. Legacy data rates are supported for backward compatibility.

The Seagull 52 supports industrial temperatures from -40°C to +85°C and can be used in front, mid and back haul and high density 5G wireless data centers.

About Seagull 202

The Seagull 202 DSP is a full-duplex product that can be used in next-generation QSFP28 4x50Gbps optical transceivers for high-density data centers.


Samples of Seagull 52 and Seagull 202 are available immediately.
