Credo introduced a DSP for optical modules used in 5G front- and mid-haul wireless networks.
The Credo Seagull 50, CFD10101, is a versatile full-duplex product that can be used in next-generation QSFP28, DSFP, and SFP56 pluggable optical transceivers. It supports 50Gbps SR/DR/FR/LR and ER applications based on PAM4 modulation.
Seagull 50 operates over the full industrial temperature range of -40oC to +85oC module case and is ideal for use in datacenters and 5G wireless/eCPRI front-, mid- and backhaul applications.
The DSP can be used as a gearbox or retimer. In gearbox mode, the IC is configured as two lanes of 24.33-25.78Gbps NRZ on the host side to one lane of 50.135-53.125Gbps PAM4 on the line side. In retimer mode, the DSP is configured as one lane of 50.135-53.125Gbps PAM4 to one lane of 50.135-53.125Gbps PAM4.
