622Mbps, 3.3V Clock-Recovery and  
Data-Retiming IC with Limiting Amplifier  
MAX376  
_____________________General Description  
____________________________Features  
Single +3.3V or +5.0V Power Supply  
The MAX3676 is a complete clock-recovery and data-  
retiming IC incorporating a limiting amplifier. It is intend-  
ed for 622Mbps SDH/SONET applications and operates  
from a single +3.3V supply.  
Exceeds ITU/Bellcore SDH/SONET Regenerator  
Specifications  
Low Power: 237mW at +3.3V  
The MAX3676 is designed for both section-regenerator  
and terminal-receiver applications in OC12/STM-4 trans-  
mission systems. Its jitter performance exceeds all  
SONET/SDH specifications.  
Selectable Data Inputs, Differential PECL or  
Analog  
Received-Signal-Strength Indicator  
The MAX3676 has two differential input amplifiers: one  
accepts positive-referenced emitter-coupled logic  
(PECL) levels, while the other accepts small-signal ana-  
log levels. The analog inputs access the limiting amplifi-  
er stage, which provides both a received-signal-strength  
indicator (RSSI) and a programmable-threshold loss-of-  
power (LOP) monitor. Selecting the PECL amplifier dis-  
ables the limiting amplifier, conserving power. A  
loss-of-lock (LOL) monitor is also incorporated as part of  
the fully integrated phase-locked loop (PLL).
