General Description

The MAX3676 is a complete clock-recovery and data retiming IC incorporating a limiting amplifier. It is intended for 622Mbps SDH/SONET applications and operates from a single +3.3V supply.

The MAX3676 is designed for both section-regenerator and terminal-receiver applications in OC12/STM-4 transmission systems. Its jitter performance exceeds all SONET/SDH specifications.
