20 Claims

1. A method comprising:

accessing, by a transmitter physical layer (PHY) controller, data for transmission to a receiver PHY controller over a network connection;

randomizing a delimiter independently of randomizing the data;

selecting a disparity reset value based on the randomized delimiter to generate an initial running disparity;

encoding the randomized data based on the initial running disparity;

generating a frame that includes the encoded randomized data and the randomized delimiter; and

transmitting the frame from the transmitter PHY controller to the receiver PHY controller.
