Abstract
Apparatus and method for communication is disclosed. In an apparatus, at least one transmission circuit is configured to provide an output alignment marker representing an exclusive disjunction of an orthogonal sequence and an input alignment marker. A multiplexer is configured to multiplex the output alignment marker with payload data for transmission via a communication lane of a plurality of communication lanes.

An apparatus for transmission, comprising:
- a plurality of communication lanes;
- a plurality of transmission circuits configured to provide, for each communication lane of the plurality of communication lanes, an output alignment marker representing an exclusive disjunction of an orthogonal sequence of a plurality of orthogonal sequences and an input alignment marker;
- and
- a plurality of multiplexers, wherein each multiplexer is configured to multiplex an output alignment marker with payload data for a communication lane of the plurality of communication lanes for transmission via a communication lane of the plurality of communication lanes.
