ANY-RATE I 2C PROGRAMMABLE XO/VCXO

The SI570 XO / SI571 VCXO utilizes Silicon Laboratories 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 frequencies to 1400 MHz with <1 ppb resolution. The device is programmed via an I 2C serial Interface Unlike traditional XO VCXOs where a different crystal is required for each output frequency, the Si57x uses one fixed- frequency crystal and a DSPLL Clock synthesis IC to provide any-rate frequency operation. This IC-based approach allows the crystal Resonator to provide exceptional frequency stability and reliability. In addition, DSPLL Clock synthesis provides superior supply noise rejection, simplifying the task of generating low-jitter Clocks in noisy environments typically found in Communication systems.
