Description
The Si597 quad frequency VCXO utilizes Silicon Laboratories’ advanced
DSPLL
®
circuitry to provide a low-jitter clock for all output frequencies. The
Si597 is available with one of four pin-selectable ouput frequencies from 10
to 810 MHz. Unlike traditional VCXOs, where a different crystal is required
for each output frequency, the Si597 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 supply noise rejection, simplifying
the task of generating low-jitter clocks in noisy environments. The Si597 IC-
based quad frequency VCXO is factory-configurable for a wide variety of
user specifications including frequencies, supply voltage, output format,
tuning slope, and absolute pull range (APR). Specific configurations are
factory programmed at time of shipment, thereby eliminating the long lead
times associated with custom oscillators.
