Description
The Si532 dual frequency XO utilizes Silicon Laboratories advanced
DSPLL
The Si532 is available with any-rate output frequency from 10 to 945 MHz
and selected frequencies to 1400 MHz. Unlike traditional XOs where a
different crystal is required for each output frequency, the Si532 uses one
fixed crystal frequency to provide a wide range of output frequencies. This
IC based approach allows the crystal resonator to be optimized for superior
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 often found in communication
systems. The Si532 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 Si532 at the time of
shipment, thereby eliminating the long lead times associated with custom
oscillators.
