MAX3875E/D中文资料美信数据手册PDF规格书

General Description

The MAX3875 is a compact, low-power clock recovery and data retiming IC for 2.488Gbps SDH/SONET applications. The fully integrated phase-locked loop recovers a synchronous clock signal from the serial NRZ data input, which is retimed by the recovered clock.
