SI5350A-B05941-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350A-B05941-GMR is a factory-programmable CMOS clock generator manufactured by Skyworks Solutions. It utilizes a PLL and MultiSynth architecture to generate up to eight non-integer-related frequencies ranging from 2.5 kHz to 200 MHz with 0 ppm error. The device operates on a single supply voltage of 1.8 V, 2.5 V, or 3.3 V for both core and output buffers. It features low period jitter typically below 70 ps pp and supports configurable spread spectrum modulation. The component is housed in a 20-QFN package and requires a 25 MHz or 27 MHz crystal reference.
