Description (Top View) The Si530/531 XO utilizes Silicon Laboratories advanced DSPLL circuitry to provide a low jitter clock at high frequencies. The Si530/531 is available 1 6 V NC DD with any-rate output frequency from 10 to 945 MHz and select frequencies to 1400 MHz. Unlike a traditional XO, where a different crystal is required for OE 2 5 CLK each output frequency, the Si530/531 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, GND 3 4 CLK+ DSPLL clock synthesis provides superior supply noise rejection, simplifying the task of generating low jitter clocks in noisy environments typically found in Si530 (LVDS/LVPECL/CML) communication systems. The Si530/531 IC based XO is factory configurable for a wide variety of user specifications including frequency, supply voltage, output format, and temperature stability. Specific configurations are factory V 1 6 DD OE programmed at time of shipment, thereby eliminating long lead times associated with custom oscillators.
