Product Overview
The Skyworks Solutions Si590/591 Crystal Oscillator (XO) leverages advanced DSPLL circuitry to deliver a low jitter clock with a maximum jitter of 1 ps, operating across a wide frequency range of 10 MHz to 810 MHz. Unlike traditional XOs, this IC-based solution utilizes 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 generating low jitter clocks in noisy communication system environments. The Si590/591 is factory configurable for user-specified frequency, supply voltage, output format, and stability, eliminating long lead times associated with custom oscillators. It is well-suited for applications including SONET/SDH, networking, SD/HD SDI/3G SDI video, test and measurement, storage, and FPGA/ASIC clock generation.
