Description

(Top View)

The Si550 VCXO utilizes Silicon Laboratories’ advanced DSPLL circuitry to

provide a low-jitter clock at high frequencies. The Si550 supports any

frequency from 10 to 945 MHz and select frequencies to 1417 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.
