The OP4004B is a voltage-controlled SAW clock (VCSC) designed for phase-locked loop (PLL) applications in optical data communications systems. The differential outputs of the OP4004B 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 OP4004B differential outputs feature +/-1% symmetry, and can be DC-configured to drive a wide range of high-speed logic families. The OP4004B is packaged in a hermetic metal-ceramic LCC.
