Abstract
The invention relates to a method, a circuit, and an apparatus for detecting distortion in spread spectrum signals. An edge in a spread spectrum clock signal is identified based on a reference clock signal. The edge data is then provided to a set of counters which are incremented corresponding to an identified edge. Each bit of a respective output of the counters are provided to a respective OR gate of a set of OR gates. An OR gate from the set of OR gates corresponding to a selected bit then outputs an indication of whether distortion exists in the spread spectrum clock signal.
