FA1431 / W-TX-28-SR4 (4x28-Gbps Quad CDR with Integrated VCSEL Drivers)

General description

FA1431, or W-TX-28-SR4, is a 4x28-Gbps quad-channel CDR with integrated VCSEL drivers. Typical applications include 100G-SR4 QSFP28 active optical cables (AOC) and transceivers. Under CDR modes, each channel supports 24.33~28.05-Gbps full-rate or 12.165~14.025-Gbps half-rate retiming. It also provides CDR bypass mode for low-power applications.
