Patent ID: 8923417

Claim:
A method of serial data communication, the method comprising: encoding data to be transmitted by a communication protocol encoder of a transmitter to generate protocol-encoded data; serializing the protocol-encoded data to generate serialized data; encoding the serialized data for power-delivery-network noise reduction (PNR) using a PNR encoder so as to generate PNR-encoded serial data; providing the serialized data to a first input of a first selector; providing the PNR-encoded serial data to a second input of the first selector; outputting the serialized data by the first selector when a first control signal indicates a first operating mode in which said encoding is disabled; outputting the PNR-encoded serial data by the first selector when the first control signal indicates a second operating mode in which said encoding is enabled; driving onto a communication channel the serialized data signal in the first operating mode and the PNR-encoded serial data signal in the second operating mode.
