Abstract
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.
Claims27
A receiver operable to receive quinary symbols encoded according to encoding parameters, the symbols being skewed with respect to each other by respective skew intervals, the receiver comprising:
- a physical coding sublayer (PCS) receiver encoder generator operable to regenerate at least a portion of the encoding parameters;
- and
- a PCS receiver core circuit operable to generate skew adjustment signals for adjusting the skew intervals of the quinary encoded symbols in response to at least a portion of the regenerated encoding parameters.
In a receiver arranged to receive quinary symbols encoded according to encoding parameters, the symbols being skewed with respect to each other by respective skew intervals, a method comprising the operations of:
- regenerating at least a portion of the encoding parameters;
- and
- decoding the quinary encoded symbols in response to at least a portion of the regenerated encoding parameters.
A system comprising:
- a medium independent interface;
- a communication medium including a plurality of twisted pair cables;
- and
- a receiver coupled to the medium independent interface and the communication medium, the receiver being operable to receive quinary symbols encoded according to encoding parameters, the symbols being skewed with respect to each other by respective skew intervals, the receiver comprising:
- a PCS receiver encoder generator operable to regenerate at least a portion of the encoding parameters;
- and
- a physical coding sublayer (PCS) receiver core circuit operable to generate skew adjustment signals for adjusting the skew intervals of the quinary encoded symbols in response to at least a portion of the regenerated encoding parameters.
