Product Description
Product Overview
The Si590/591 is a Crystal Oscillator (XO) utilizing Skyworks Solutions' advanced DSPLL circuitry to deliver 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 design with DSPLL clock synthesis provides 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.
