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. Unlike traditional XOs, it employs a single fixed crystal to generate a wide range of output frequencies, ensuring exceptional frequency stability and reliability. Its IC-based design offers superior supply noise rejection, simplifying clock generation in noisy communication system environments. The Si535/536 is factory programmed, eliminating long lead times associated with custom oscillators. It is ideal for demanding applications such as 10/40/100G data centers, 10G Ethernet switches/routers, Fibre Channel/SAS/storage, enterprise servers, networking, and telecommunications.
