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