Description
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
via an I
2
C serial interface. Unlike traditional XO/VCXOs where a different
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.
