General Description

The MAX3877/MAX3878 are compact, low-power clock recovery and data retiming ICs for 2.488Gbps SONET/ SDH applications.

The fully integrated phase-locked loop (PLL) recovers a synchronous clock signal from the serial NRZ data input, which is retimed by the recovered clock.

An additional 2.488Gbps serial input is available for system loopback diagnostic testing, or this input can be connected to a 155MHz reference clock to maintain a valid clock output in the absence of data transitions.
