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, offering exceptional frequency stability and reliability. Its IC-based approach and DSPLL clock synthesis provide superior supply noise rejection, making it ideal for noisy communication system environments. The Si590/591 is factory configurable for frequency, supply voltage, output format, and stability, eliminating long lead times for custom oscillators.
