Typical Operating Circuit
General Description
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.
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.
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).
