Description The Si596 dual-frequency VCXO utilizes Skyworks Solutions advanced (Top View) DSPLL circuitry to provide a low-jitter clock at high frequencies. The Si596 is available with any-rate output frequency from 10 to 810 MHz. Unlike V C 1 6 V DD traditional VCXOs, where a different crystal is required for each output frequency, the Si596 uses one fixed crystal to provide a wide range of output frequencies. This IC-based approach allows the crystal resonator to provide 2 5 CLK FS exceptional frequency stability and reliability. In addition, DSPLL clock synthesis provides supply noise rejection, simplifying the task of generating GND 3 4 CLK+ low-jitter clocks in noisy environments. The Si596 IC-based VCXO is factory-configurable for a wide variety of user specifications including frequency, supply voltage, output format, tuning slope, and absolute pull range (APR). Specific configurations are factory programmed at time of shipment, thereby eliminating the long lead times associated with custom oscillators.
