Product Overview
The Skyworks Si590/591 is a 1 ps MAX JITTER CRYSTAL OSCILLATOR (XO) that utilizes advanced DSPLL circuitry to provide a low jitter clock at high frequencies, supporting any frequency from 10 to 810 MHz. Unlike traditional XOs, it uses a single fixed crystal for a wide range of output frequencies, ensuring exceptional frequency stability and reliability. Its IC-based approach offers superior supply noise rejection, simplifying clock generation in noisy communication system environments. The Si590/591 is factory configurable for frequency, supply voltage, output format, and stability, with specific configurations programmed at shipment to eliminate long lead times.
