Product Description
Product Overview
The Skyworks Si590/591 is a 1 ps MAX JITTER CRYSTAL OSCILLATOR (XO) operating from 10 MHz to 810 MHz. Utilizing advanced DSPLL circuitry, it offers a low jitter clock at high frequencies. Unlike traditional XOs, it uses a single fixed crystal to achieve a wide range of output frequencies, providing exceptional frequency stability and reliability. Its IC-based design offers 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, with specific configurations programmed at the time of shipment to minimize lead times.
