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
2
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-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.
