Low-Jitter Frequency Synthesizer with Selectable Input Reference

Active: In Production.

The MAX3671 is a low-jitter frequency synthesizer that accepts two reference clock inputs and generates nine phase-aligned outputs. The device features 40kHz jitter transfer bandwidth, 0.3ps_RMS (12kHz to 20MHz) integrated phase jitter, and best-in-class power-supply noise rejection (PSNR), making it ideal for jitter cleanup, frequency translation, and clock distribution in Gigabit Ethernet applications.

The MAX3671 operates from a single +3.3V supply and typically consumes 400mW. The IC is available in an 8mm x 8mm, 56-pin TQFN package, and operates from -40°C to +85°C.
