Product Description
Product Overview
The Skyworks Si590/591 is a Crystal Oscillator (XO) utilizing advanced DSPLL circuitry to deliver low jitter clock signals 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 output, ensuring exceptional frequency stability and reliability. Its DSPLL clock synthesis 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, enabling rapid deployment without long lead times.
