Description
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.
