MAX3875A

2.5Gbps, Low-Power, +3.3V Clock Recovery and Data Retiming IC

The Low-Power Way to Receive Clean 2.5Gbps Signals


Please check latest availability status for a specific part variant.

Description

The MAX3875A 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. Differential PECL-compatible outputs are provided for both clock and data signals, and an additional 2.488Gbps serial input is available for system loopback diagnostic testing. The device also includes a TTL-compatible loss-of-lock (LOL-bar) monitor.

The MAX3875A is designed for both section-regenerator and terminal-receiver applications in OC-48/STM-16 transmission systems. Its jitter performance exceeds all of the SONET/SDH specifications.

This device operates from a single +3.3V to +5.0V supply over a -40°C to +85°C temperature range. The typical power consumption is only 400mW with a +3.3V supply. It is available in a 32-pin TQFP package, as well as in die form.
