Credo offers 100G mux/retimer based on 50-Gbps PAM4
Serializer-deserializer (SerDes) specialist Credo Semiconductor has introduced the Credo CMX12550 mux, a sub 1-W multiplexer (mux)/retimer device. It is designed to support 100-Gbps optical modules with 50-Gbps per lambda throughput based on PAM4. The mux/retimer, which is now sampling, will support four bidirectional 25-Gbps NRZ lanes as well as two 50-Gbps PAM4 bidirectional lanes, the company says.
