Description
The Si535/536 XO utilizes Silicon Laboratories’ advanced DSPLL® circuitry
to provide an ultra low jitter clock at high-speed differential frequencies.
Unlike a traditional XO, where a different crystal is required for each output
frequency, the Si535/536 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 Si535/536 IC based XO is factory programmed
at time of shipment, thereby eliminating long lead times associated with
custom oscillators.
