Description The Si532 dual frequency XO utilizes Silicon Laboratories advanced DSPLL® circuitry to provide a very low jitter clock for all output frequencies. .. The Si532 is available with any-rate output frequency from 10 to 945 MHz and selected frequencies to 1400 MHz. Unlike traditional XOs where a different crystal is required for each output frequency, the Si532 uses one fixed crystal frequency to provide a wide range of output frequencies. This IC based approach allows the crystal resonator to be optimized for superior 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 often found in munication systems. The Si532 IC based XO is factory configurable for a wide variety of user specifications including frequency, supply voltage, and output format. Specific configurations are factory programmed into the Si532 at the time of shipment, thereby eliminating the long lead times associated with custom oscillators.
