Description

The Si534 quad frequency XO utilizes Silicon Laboratories’ advanced

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 Si534 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 superior supply noise rejection,

simplifying the task of generating low jitter clocks in noisy environments

typically found in communication systems. The Si534 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.
