570ACA001516DGR Description

 High performanceinstrumentation Low-jitter clock generation Optical modules Clock and data recoveryThe Si570 XO/Si571 VCXO utilizes Skyworks Solutions’ advanced DSPLL®circuitry to provide a low-jitter clock at any frequency. The Si570/Si571 are user-programmable to any output frequency from 10 to 945 MHz and select frequenciesto 1400 MHz with <1 ppb resolution. The device is programmed via an I2C serialinterface. Unlike traditional XO/VCXOs where a different crystal is required foreach output frequency, the Si57x uses one fixed-frequency crystal and a DSPLLclock synthesis IC to provide any-frequency operation. This IC-based approachallows the crystal resonator to provide exceptional frequency stability andreliability. In addition, DSPLL clock synthesis provides superior supply noiserejection, simplifying the task of generating low-jitter clocks in noisy environmentstypically found in communication systems.
