MAX3875 Datasheet 2.5gbps / Low-power / #.3v Clock Recovery And Data Retiming Ic

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-4789; Rev 0; 10/98 2.5Gbps, Low-Power, +3.3V Clock Recovery and Data Retiming.

General Description

The MAX3875 is a pact, 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.

Differential PECL-patible outputs are provided for both clock and data signals, and an additional 2.488Gbps serial input is available for system loopback diagnostic testing.
