FA2130B / W-TRX-28-LR (28-Gbps Dual CDR with Integrated DML Driver and LA)

General description

FA2130B, or W-TRX-28-LR, is a highly integrated optical transceiver IC with integrated TX CDR, RX CDR, DML driver and limiting amplifier. Typical application is 25G-LR SFP28 transceiver. It directly drives an external TOSA and receives signal from an external ROSA. It uses a hermetic BGA package and supports both CPRI and 25GbE.
