General Description
The MAX3672 is a low-jitter 155MHz/622MHz reference
clock generator IC designed for system clock distribution
and frequency synchronization in OC-48 and OC-192
SONET/SDH and WDM transmission systems. The
MAX3672 integrates a phase/frequency detector, an
operational amplifier (op amp), prescaler dividers, and
input/output buffers. Using an external VCO, the
MAX3672 can be configured easily as a phase-lock loop
with bandwidth programmable from 30Hz to 10kHz.
The MAX3672 operates from a single +3.3V or +5.0V
supply and dissipates 150mW (typ) at 3.3V. The operat-
ing temperature range is -40°C to +85°C.
