Description

The Si532 dual frequency XO utilizes Silicon Laboratories’ advanced

DSPLL

circuitry to provide a low jitter clock at high frequencies. The Si532 is

available with any-rate output frequency from 10 to 945 MHz and select

frequencies to 1400 MHz. Unlike a traditional XO where a different crystal is

required for each output frequency, the Si532 uses one fixed crystal

frequency 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 superior

supply noise rejection, simplifying the task of generating low jitter clocks in

noisy environments typically found in communication systems. The Si532 IC

based XO is factory configurable for a wide variety of user specifications

including frequency, supply voltage, output format, and temperature stability.

Specific configurations are factory programmed at time of shipment, thereby

eliminating long lead times associated with custom oscillators.
