Description

The Si550 VCXO utilizes Silicon Laboratories’ advanced DSPLL

circuitry to

provide a low-jitter clock at high frequencies. The Si550 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 Si550 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 superior supply noise rejection,

simplifying the task of generating low-jitter clocks in noisy environments

typically found in communication systems. The Si550 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.
