MAX3675

622Mbps, Low-Power, 3.3V Clock-Recovery and Data-Retiming IC with Limiting Amplifier


Please check latest availability status for a specific part variant.

Description

The MAX3675 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 MAX3675 has two differential input amplifiers: one accepts PECL levels, while the other accepts small-signal analog levels. The analog inputs access the limiting amplifier stage, which provides both a received-signal-strength indicator (RSSI) and a programmable-threshold loss-of-power (LOP) monitor. Selecting the PECL amplifier disables the limiting amplifier, conserving power. A loss-of-lock (LOL) monitor is also incorporated as part of the fully integrated PLL.
