available with any-frequency 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 Si532 uses one fixed crystal
frequency 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 Si532 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.
