Credo Technology Group Holding Ltd. announced the availability of Seagull 452 family of high-performance, low-power optical Digital Signal Processors (DSPs). The family consists of the octal channel Seagull 452, the quad channel Seagull 252 and the dual channel Seagull 152 DSPs. All devices come with integrated VCSEL, EML and SiPho drivers.

The Seagull 452 family incorporates Credo's fourth generation DSP technology on the electrical host interface and the optical interface. On the optical side, the latest performance enhancements allow customers to relax the optical component specifications, thereby increasing manufacturing yields and lowering costs. The new Seagull 452 boasts exceptionally low-power consumption and is targeted at the burgeoning 400G Active Optical Cable (AOC) market for AI networks.

This breakthrough is achieved while maintaining superior link performance, compact size and optimized cost that makes this product line a superior choice for all 400G, 200G and 100G AOC and transceiver applications. Seagull 452 is a versatile full-duplex device that can be used in next generation 8x50Gbps QSFP-DD optical transceivers or AOCs for 400Gbps SR8/DR8/DR8/FR8/LR8 applications using PAM4 modulation. Seagull 252 can be used in next generation 4x50GbpsQSFP56 optical transceivers or Aocs in 200Gbps SR4/DR4/DR4/LR4 applications using PAM4 modulation; Seagull 152 can be used in 2x50Gbps QSFS28, SFP-DD or DSFP optical transceivers or A OCs and supports 100Gbps SR2/DR2/DR2/LR2 applications.

All members of the Seagull 452 family support 25 Gbps NRZ operation for backwards compatibility. Key Features of the Seagull 45 2 DSP Family: Fourth generation DSPs on host and line side; Line side Rx performance-enhancing features specific to optical link and component impairments; Integrated VCSEL drivers with programmable bias and modulation currents; Integrated EML and SiPho driver with programmable output swing and equalization; Host side supports extended PCB reach; Use with Teal 200 4x50G TIA for a complete optical chipset solution. Availability: Samples of the Seagull 451 family are all available now.

Interested customers should contact. All Credo product offerings are supported by evaluation boards, simulation models, characterization reports, reliability reports, design libraries and a full set of supporting documentation.
