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 utilizes 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. Factory programmed at shipment, it eliminates long lead times associated with custom oscillators. Available in a 5 x 7 mm package with LVPECL and LVDS outputs, and 3.3 V or 2.5 V supply options, it is suitable for demanding applications such as 10/40/100G data centers, Ethernet switches/routers, Fibre Channel/SAS/storage, enterprise servers, networking, and telecommunications.
