SiLSI5356A-B-GM

Overview

The SI5356A-B-GM is a highly flexible, I2C programmable clock generator capable of synthesizing any frequency from 1 to 200 MHz on each of its eight outputs. Using MultiSynth fractional divider technology, it enables the generation of multiple unrelated frequencies with 0 ppm synthesis error, replacing several crystal oscillators with a single IC.

Why Choose This Part

The primary advantage is the MultiSynth technology which provides 0 ppm frequency accuracy across eight independent outputs, significantly reducing PCB footprint and BOM cost. It also features configurable spread spectrum for EMI reduction and integrated non-volatile memory (NVM) for storing custom power-up configurations.

Applications

Getting Started

Engineers should use the Silicon Labs ClockBuilder Pro software to calculate frequency configurations and register maps. The device can be customized via the I2C interface or pre-programmed by the factory; for prototyping, the Si5356-EVB evaluation board provides a direct hardware platform for testing output performance.
