Quartz SAW Stabilized Differential Output Technology Very Low Jitter Fundamental-Mode Operation at 644.53125 MHz Voltage Tunable for Phase Locked Loop Applications Timing Reference for 10G Optical Ethernet Communications Systems
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.
