Description

(Top View)

The Si530/531 XO utilizes Silicon Laboratories’ advanced DSPLL circuitry

to provide a low jitter clock at high frequencies. The Si530/531 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 Si530/531 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 Si530/531 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.
