Description

(Top View)

The 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 frequencies

V_DD

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-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.
