The Si595 is available with any-rate output frequency from 10 to 810 MHz. Unlike traditional VCXOs, where a different crystal is required for each output frequency, the Si595 uses one fixed crystal to provide a wide range of output frequencies. This ICbased approach allows the crystal resonator to provide exceptional frequency stability and reliability. In addition, DSPLL clock synthesis provides supply noise rejection, simplifying the task of generating low-jitter clocks in noisy environments. The Si595 IC-based VCXO is factoryconfigurable for a wide variety of user specifications including frequency, supply voltage, output format, tuning slope, and absolute pull range (APR).
