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

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 Si554 IC-based VCXO is factory-configurable for a wide

variety of user specifications including frequency, supply voltage, output

format, tuning slope, and temperature stability. Specific configurations are

factory-programmed at time of shipment, thereby eliminating the long lead

times associated with custom oscillators.
