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.

1. An apparatus, comprising:
a transceiver circuit comprising:
a transmitter circuit configured to transmit a signal;a receiver circuit configured to receive the signal;a generator configured to generate a composite jitter including a plurality of multi-tone jitter components; anda processor operable to digitally inject the composite jitter into the receiver circuit and/or the transmitter circuit of the transceiver circuit for testing a jitter tolerance associated with the transceiver circuit based on the signal and the injected composite jitter.
