SI5350C-B05987-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5350C-B05987-GTR is a factory-programmable CMOS clock generator manufactured by Skyworks Solutions. It utilizes a dual PLL and MultiSynth fractional divider architecture to generate up to eight non-integer-related frequencies ranging from 2.5 kHz to 200 MHz with 0 ppm error. The device supports glitchless frequency changes, configurable spread spectrum, and static phase offsets. It operates on core supply voltages of 1.8 V, 2.5 V, or 3.3 V and output buffer voltages of 1.8 V, 2.5 V, or 3.3 V. The part number suffix 'GTR' indicates the component is supplied in tape and reel packaging.
