1. A data communication system, comprising:

  • a transmission line;

    a first integrated circuit coupled to the transmission line and including a transmitter, the transmitter comprisingan encoder, having a data input, that encodes an input data stream to produce a sequence of codewords, wherein codewords in the sequence are members of a set of codewords representing data in the input data stream, and the members of the set are substantially DC balanced; and

    a driver, coupled to the encoder, that drives the sequence of codewords within a corresponding sequence of symbol cells on the transmission line, wherein the driver drives the sequence of codewords with power of less than 100 picoJoules per bit; and

    a second integrated circuit coupled to the transmission line and including a receiver, the receiver comprisingan input to receive the sequence of codewords.
