Description  
(Top View)  
®
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.
