SI5338B-B-GMR
Overview
The SI5338B-B-GMR is a highly flexible, I2C-programmable clock generator capable of synthesizing up to four independent frequencies on its outputs. Utilizing Skyworks proprietary MultiSynth technology, it supports frequencies up to 350MHz with ultra-low phase jitter of 0.7 ps RMS, making it ideal for high-speed data communications and timing synchronization.
Why Choose This Part
This IC replaces up to four discrete crystal oscillators with a single chip, significantly reducing PCB footprint and BOM complexity. Its ability to accept a wide range of input references (CML, CMOS, HCSL, LVDS, etc.) and provide independent frequency and phase adjustment per output offers unparalleled design flexibility in complex mixed-signal environments.
Applications
Key Specifications
Getting Started
Designers can use the Skyworks ClockBuilder Pro software to configure the internal registers and generate the necessary I2C hex files. For hardware evaluation, look for the Si5338-EVB evaluation board which allows for real-time testing of different output configurations and signal integrity through SMA connectors.
