Overview

The SI5332A-D-GM3 is a high-performance clock generator that utilizes Skyworks Solutions' proprietary MultiSynth technology to provide any-frequency synthesis on up to 12 outputs. It supports multiple differential and single-ended clock formats including HCSL, LVDS, LVPECL, and LVCMOS, making it a versatile timing hub for complex digital systems. The device operates from a wide supply range of 1.71V to 3.63V and features integrated power supply filtering to reduce board space and external component count.

Why Choose This Part

The SI5332A-D-GM3 eliminates the need for multiple discrete crystals and oscillators by providing 12 outputs from a single reference. Its MultiSynth technology ensures 0 ppm frequency synthesis error across a wide range of frequencies up to 333.33MHz, while the internal LDOs provide excellent power supply noise rejection to maintain low jitter in noisy environments.

Applications

Network Switches and Routers
Generating multiple synchronized low-jitter clocks for high-speed Ethernet and backplane communication.
PCIe Gen 1/2/3/4/5 Clocking
Providing compliant HCSL clocks with programmable spread spectrum for EMI reduction in server and storage applications.

Getting Started

Configuration is typically performed using the Skyworks ClockBuilder Pro software, which allows users to define frequencies and output formats then generate a configuration file. For hardware evaluation, the SI5332-6EX-EVB provides a platform to test the device's performance and I2C programmability. Design engineers should ensure the 48-QFN center pad is properly soldered to a ground plane for thermal dissipation and signal integrity.
