Overview
The GN2504C is a uni-directional quad-CDR retimer, rated for the industrial temperature ranges and designed for reference-free 25-28Gbps signal conditioning on linecards interfacing next-generation modules such as CFP2, CFP4 and QSFP28 and to interface next-generation 25-28Gbps backplanes. It can be used in 5G base station equipment such as active antenna and base band units.
