A physical coding sublayer (PCS) transmitter circuit generates a plurality of encoded symbols according to a transmission standard. A symbol skewer skews the plurality of encoded symbols within a symbol clock time. A physical coding sublayer (PCS) receiver core circuit decodes a plurality of symbols based on encoding parameters. The symbols are transmitted using the encoding parameters according to a transmission standard. The received symbols are skewed within a symbol clock time by respective skew intervals. A PCS receiver encoder generator generates the encoding parameters.
