A LOW POWER, DC-BALANCED SERIAL LINK
First Claim
1. A method for receiving a sequence of codewords within a corresponding sequence of symbol cells on a transmission line, the method comprising:
- integrating codewords in a received sequence of codewords to produce output representing the sequence of codewords, including 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, wherein there is one codeword per symbol cell, and codewords in the received sequence are members of a set of codewords representing data in an encoded data stream, and the members of the set are substantially DC balanced; and
producing an output data stream based on the output.

Abstract
A receiver for a data communication system which 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 based on the samples.
