Description
®
The Si530 XO utilizes Silicon Laboratories advanced DSPLL circuitry to
provide a low jitter clock at high frequencies. The Si530 is available with
any-rate output frequency from 10 to 945 MHz and selected frequencies to
1400 MHz. Unlike a traditional XO, the crystal frequency inside the Si530 is
fixed for a wide range of output frequencies. This IC based approach allows
the crystal resonator to be optimized for superior frequency stability,
reliability and mechanical integrity. 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 IC based XO is factory configurable for a wide variety of
user specifications including frequency, supply voltage and output format.
Specific configurations are factory programmed into the Si530 at time of
shipment, thereby eliminating the long lead times associated with custom
oscillators.
