SI5351A-B09991-GT Description

The Si5351 is an I2C configurable clock generator that is ideally suited forreplacing crystals, crystal oscillators, VCXOs, phase-locked loops (PLLs), andfanout buffers in cost-sensitive applications.Based on a PLL/VCXO + high resolution MultiSynthfractional dividerarchitecture, the Si5351 can generate any frequency up to 200 MHz on each ofits outputs with 0 ppm error. Three versions of the Si5351 are available to meet awide variety of applications.The Si5351A generates up to 8 free-running clocks using an internal oscillatorfor replacing crystals and crystal oscillators. The Si5351B adds an internalVCXO and provides the flexibility to replace both free-running clocks andsynchronous clocks. It eliminates the need for higher cost, custom pullablecrystals while providing reliable operation over a wide tuning range. TheSi5351C offers the same flexibility but synchronizes to an external referenceclock (CLKIN).Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.comRev. 1.3 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • August 27, 2021
