Abstract:
A method and an apparatus for correcting baseline wander is disclosed. The method and apparatus may include receiving a serial data stream that encodes a plurality of data symbols, and determining an average magnitude of a first data value included in one or more data symbols of a subset of the plurality of data symbols, and an average magnitude of a second value included in the one of more data symbols of the subset of the plurality of data symbols. A common mode operating point of an equalizer circuit may be adjusted using the average magnitude of the first data value and the average magnitude of the second data value.
