Low-Jitter Frequency Synthesizer With Selectable Input Reference

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, 0.3psRMS (12kHz to 20MHz) inte- grated phase jitter, and best-in-class power-supply noise rejection (PSNR), making it ideal for jitter clean- up, 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. By Maxim Integrated Products
