ABSTRACT:
A data communication system comprises a transmission line between first and second integrated circuits. An encoder on the first integrated circuit 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, such as a Manchester encoded symbol set. An integrating circuit on the second integrated circuit integrates codewords by integrating for a first interval with a positive polarity within a particular symbol cell, and integrating for a second interval with a negative polarity within the particular symbol cell, to produce output representing the codewords. A sense circuit produces an output data stream.
