Description (Top View) The Si590/591 XO utilizes Silicon Laboratories advanced DSPLL circuitry to provide a low jitter clock at high frequencies. The Si590/591 supports any frequency from 10 to 810 MHz. Unlike a traditional XO, where a unique 1 6 V NC DD crystal is required for each output frequency, the Si590/591 uses one fixed crystal to provide a wide range of output frequencies. This IC based OE 2 5 CLK approach allows the crystal resonator to provide exceptional frequency stability and reliability. In addition, DSPLL clock synthesis provides superior GND 3 4 supply noise rejection, simplifying the task of generating low jitter clocks in CLK+ noisy environments typically found in communication systems. The Si590/591 IC based XO is factory configurable for a wide variety of user Si590 (LVDS/LVPECL/CML) specifications including frequency, supply voltage, output format, and stability. Specific configurations are factory programmed at time of shipment, thereby eliminating long lead times associated with custom oscillators.
