A communications system that may include a transmitter, a receiver, connected over a communications network. A communication link on the communications network may transfer data between the transmitter and the receiver. The system may also include a logic unit to scramble a plurality of portions of the data at the transmitter based upon the communication link and may unscramble the plurality of portions of the data at the receiver. As a result, the logic unit may provide improved performance of the communication link and/or reduced power consumption of the communication link.
