General Description
The MAX3670 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
MAX3670 integrates a phase/frequency detector, an
operational amplifier (op amp), prescaler dividers and
input/output buffers. Using an external VCO, the
MAX3670 can be configured easily as a phase-lock loop
with bandwidth programmable from 15Hz to 20kHz.
The MAX3670 operates from a single +3.3V or +5.0V
supply, and dissipates 150mW (typ) at 3.3V. The operat-
ing temperature range is from -40°C to +85°C. The chip
is available in a 5mm
5mm, 32-pin QFN package.
