644.53125MHz Optical Timing Clock

The OP4012B is a voltage-controlled SAW Clock (VCSC) designed for phase-locked loop (PLL) applications in optical data Communications systems. The differential outputs of the OP4012B are generated by high-Q, fundamental mode quartz surface acoustic wave (SAW) technology. This technique provides very low output jitter and phase noise, plus excellent immunity to power supply noise. The OP4012B differential outputs feature 1% symmetry, and CAN be DC-configured to drive a wide range of high-speed Logic families. The OP4012B is packaged in a hermetic metal-ceramic LCC By RF Monolithics, Inc.
