Product Overview
The Skyworks 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 ensures superior supply noise rejection, making it ideal for generating low-jitter clocks in noisy communication environments. The Si535/536 is factory programmed, offering a cost-effective and reliable solution for demanding applications.
