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.
