The Si570 XO/Si571 VCXO utilizes Silicon Laboratories’ advanced DSPLL  
circuitry to provide a low-jitter clock at any frequency. The Si570/Si571 are  
user-programmable to any output frequency from 10 to 945 MHz and select  
frequencies to 1400 MHz with <1 ppb resolution. The device is programmed

crystal is required for each output frequency, the Si57x uses one fixed-  
frequency crystal and a DSPLL clock synthesis IC to provide any-rate  
frequency operation. 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.
