Description

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

C 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.
