Description
The Si590/591 XO utilizes Silicon Laboratories’ advanced DSPLL
®
circuitry
to provide a low jitter clock at high frequencies. The Si590/591 supports any
frequency from 10 to 810 MHz. Unlike a traditional XO, where a unique
crystal is required for each output frequency, the Si590/591 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
Si590/591 IC based XO is factory configurable for a wide variety of user
specifications including frequency, supply voltage, output format, and
stability. Specific configurations are factory programmed at time of shipment,
thereby eliminating long lead times associated with custom oscillators.
