Product Description
Product Overview
The Si590/591 is a Crystal Oscillator (XO) utilizing Skyworks Solutions advanced DSPLL circuitry to provide a low jitter clock at high frequencies. It supports any frequency from 10 to 810 MHz, using a single fixed crystal for a wide range of output frequencies. This IC-based approach ensures exceptional frequency stability and reliability, with superior supply noise rejection for low jitter clock generation in noisy environments. The Si590/591 is factory configurable for frequency, supply voltage, output format, and stability, eliminating long lead times for custom oscillators.
