The CDCS501 is a spread spectrum capable, LVCMOS Input Clock Buffer for EMI reduction. The device is designed to counter common EMI problems in modern electronic designs. It accepts a 3.3V LVCMOS signal at the input and spread this signal by a small amount, centered around the input frequency. The amount of spread can be selected via 3 control pins. The Functional Table contains detailed information on the amount of spread. A 4th control pin can be used to activate or deactivate the Spread Spectrum Clock Generator.
