53G per Lane Optical DSP

Seagull 202

Seagull 202 (CFD55401) is a versatile full-duplex device with industry-leading power dissipation that can be used in next-generation QSFP56 pluggable optical transceivers. It supports 200Gbps DR4/FR4/LR4 applications based on PAM-4 modulation. Seagull 202 is ideal for use in hyperscale data centers and campuses.

Seagull 202 employs proprietary DSP technology and equalization techniques to compensate for the impairments and nonlinearities resulting from optics and fiber. Integrated drivers enable direct connection to DML lasers, eliminating the need for external drivers and simplifying the optics interface.

Seagull 202  has industry leading performance and low power dissipation. It is optimized for optimal component placement and use of standard assembly techniques for high-yield, reliable PCB designs
