Low-Jitter 155MHz/622MHz Clock Generator
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 operating temperature range is -40°C to +85°C.
Features
o Single +3.3V or +5.0V Supply o Power Dissipation: 150mW at +3.
