ZDB for Spread Spectrum Signal

Version 1
    Question: Which ZDB should be used when the input is a spread spectrum signal?



    ZDBs that has the feature of "Spread Aware" or "Spread Compatible" should be used. These parts has a wider loop band width, hence able to pass the spread signal through without loss. Some of these parts has the "S" in their name, ie. CY23S09, as supposed to the CY2309 which is not Spread Aware.
