Description

The Si595 VCXO utilizes Silicon Laboratories’ advanced DSPLL

circuitry to

provide a low-jitter clock at high frequencies. The Si595 is available with

any-rate output frequency from 10 to 810 MHz. Unlike traditional VCXOs,

where a different crystal is required for each output frequency, the Si595

uses one fixed crystal to provide a wide range of output frequencies. This IC-

based approach allows the crystal resonator to provide exceptional

frequency stability and reliability. In addition, DSPLL clock synthesis

provides supply noise rejection, simplifying the task of generating low-jitter

clocks in noisy environments. The Si595 IC-based VCXO is factory-

configurable for a wide variety of user specifications including frequency,

supply voltage, output format, tuning slope, and absolute pull range (APR).

Specific configurations are factory programmed at time of shipment, thereby

eliminating the long lead times associated with custom oscillators.
