SI5350A-B04604-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350A-B04604-GT is a factory-programmable CMOS clock generator manufactured by Skyworks Solutions. It utilizes a PLL and high-resolution 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 operates on a single fixed-frequency crystal reference of 25 or 27 MHz. It features glitchless frequency changes, configurable spread spectrum for EMI reduction, and supports static phase offsets. Electrical specifications include core and output supply voltages of 1.8 V, 2.5 V, or 3.3 V, with typical power consumption of 25 mA at the core.
