Overview

The SI5345A-D-GM is a high-performance, jitter-attenuating clock multiplier utilizing Skyworks Solutions' fourth-generation DSPLL technology. It is designed to provide ultra-low jitter clock generation for high-speed communication interfaces, supporting output frequencies up to 1.028GHz with 10 independent outputs.

Why Choose This Part

This device integrates a loop filter and supports hitless input clock switching, significantly reducing PCB complexity and BOM count. Its MultiSynth technology enables any-frequency synthesis on each of the 10 outputs with 0 ppm error, while the DCO mode allows for extremely fine frequency adjustments down to 0.001 ppb steps.

Applications

Optical Networking
Ideal for OTN, SONET/SDH, and Ethernet line cards requiring low-jitter reference clocks for high-speed SerDes.
Data Center Infrastructure
Used in high-speed switches and routers to provide synchronized, multi-format timing for PCIe, 100G/400G Ethernet, and storage interfaces.
Test and Measurement
Serves as a flexible clock source for high-precision laboratory equipment and automated test systems requiring fine frequency tuning.
