Credo intros DSP for 5G front- and mid-haul

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.

MACOM begins 100G PAM4 DSP production

MACOM announced the production release of its low power CMOS DSP-based PAM4 PHYs for next generation optical transceiver modules.

MACOM’s PAM4 PHYs with integrated DSP, forward error correction (FEC) and multiplexing functionality are designed to enable single-wavelength 50 Gbps and 100 Gbps optical transceivers.

The integrated driver is suitable for direct connection to an optical modulator, avoiding the need for a discrete driver, and, thereby, enabling reduced cost and complexity. The on-board management processor simplifies module implementation, while the flexible DSP-based equalizer supports optical links up to and beyond 10 km over single mode fiber. Optional low latency FEC enables IEEE compliant link performance with both legacy and current generation switch silicon. A full suite of test and diagnostic features enable efficient bring up and fast time to market.
