MAX3670
Low-Jitter 155MHz/622MHz Clock Generator |
Overview
|
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 operating temperature range is from -40°C to +85°C. The chip is available in a 5mm x 5mm, 32-pin QFN package. |
