FA2432 / W-RX-28-FR4 (4x28-Gbps Quad CDR with Integrated TIA's)

General description

FA2432, or W-RX-28-FR4, is a 4x28-Gbps quad-channel CDR with integrated transimpedance amplifiers (TIA). Typical applications include 100G-CWDM4 and 100G-PSM4 QSFP28 optical 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.
