Product Overview
The Skyworks Solutions Si535/536 is an ultra-low jitter Crystal Oscillator (XO) that utilizes advanced DSPLL circuitry to deliver high-speed differential frequencies with exceptional stability and reliability. Unlike traditional XOs, it employs a single fixed crystal to generate a wide range of output frequencies, simplifying system design and reducing lead times. Its IC-based approach and DSPLL clock synthesis provide superior supply noise rejection, making it ideal for generating low-jitter clocks in noisy communication environments. The Si535/536 is factory programmed for immediate use and is available in an industry-standard 5 x 7 mm package.
