Product Overview
The Si590/591 is a Crystal Oscillator (XO) from Skyworks Solutions, Inc., utilizing advanced DSPLL circuitry to deliver low jitter clock outputs at high frequencies, ranging from 10 MHz to 810 MHz. Unlike traditional XOs requiring a unique crystal for each frequency, this IC-based solution uses a single fixed crystal for broad frequency support, ensuring exceptional frequency stability and reliability. Its DSPLL clock synthesis offers superior supply noise rejection, making it ideal for generating low jitter clocks in noisy communication system environments. The Si590/591 is factory configurable for various user specifications including frequency, supply voltage, output format, and stability, with specific configurations programmed at shipment to minimize lead times.
