Description

See page 26.

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

V_DD

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.
