Description
The Si554 quad-frequency VCXO utilizes Silicon Laboratories’ advanced
DSPLL ? circuitry to provide a very low jitter clock for all output frequencies.
The Si554 is available with any-rate output frequency from 10 to 945 MHz

and selected frequencies to 1400 MHz. Unlike traditional VCXOs, where a
different crystal is required for each output frequency, the Si554 uses one
fixed crystal frequency to provide a wide range of output frequencies. This

low jitter clocks in noisy environments typically found in communication
systems. The Si554 IC-based VCXO is factory-configurable for a wide

factory-programmed at time of shipment, thereby eliminating the long lead
times associated with custom oscillators.
