Seagull 110 is a PAM4 2x50Gbps resync, while Seagull XR8 is a PAM4 8x50Gbps resync. Both devices are backward compatible and support legacy data rates.

Seagull 110 is ideal for AOC or 1: 2 transceiver links between servers with 50G PAM4 interfaces and top of rack or end of row switches. Seagull XR8 enables 400 Gbps VCSEL-based PAM4 solutions, providing a cost-effective alternative to current single-mode fiber optic connectivity in the rack. Additionally, with 1: 2, 1: 4 or 1: 8 split options, Seagull XR8 offers flexible options for network interconnection and density.

Seagull DSPs utilize Credo’s innovative design architecture for low power dissipation and excellent performance. Both devices incorporate a high performance digital signal processor (DSP) to compensate for signal degradation for low optical sensitivity and BER floor. Other features include:

  • Line side transmitters with very low electrical TDECQ and high linearity.
  • Built-in Finite Impulse Response (FIR) filters to equalize degradation associated with circuit boards, optics and connectors.
  • Receiver and transmitter performance optimization features for dedicated PLL optimal parameters and performance tuning for each channel for seamless use in disruptive applications.
  • A full suite of built-in testing features.
  • Line-side and host-side loopbacks for easy lab debugging and simplified manufacturing testing.

The entire SEAGULL family is fully compliant with the IEEE 802.3 standard with robust, repeatable performance and proven interoperability with various optical link partners and switches / ASICs.

“Next-generation data centers need continuous innovation to improve product performance while reducing overall cost of ownership and cooling requirements,” said Scott Feller, vice president of marketing at Credo. “The increase in data traffic drives continued growth of data centers with a need for assurance of supply. Credo’s new DSPs meet all customer requirements in one solution and are ideal for both optical transceiver and AOC applications, ”Scott continued.

The Seagull 110, CFD30201 and Seagull XR8, CFD60801, are available for immediate production shipments.
