DIGITALLY CONTROLLED JITTER INJECTION FOR BUILT IN SELF-TESTING (BIST)

摘要

A digitally controlled jitter injection apparatus for built in self-testing includes a transceiver circuit having a transmitter circuit and a receiver circuit. The digitally controlled jitter injection apparatus also includes a generator that generates a composite jitter including multi-tone jitter components. The digitally controlled jitter injection apparatus also includes a processor operable to digitally inject the composite jitter into a receiver circuit and/or a transmitter circuit of the transceiver circuit.
