Original Abstract Submitted

The present disclosure relates to an apparatus for increasing randomness among different communication lanes of a multilane wired data communication link. The apparatus comprises a multilane data transmitter configured to simultaneously transmit data over a first communication lane and a second communication lane of the multilane wired data communication link. The apparatus comprises a set of data scramblers configured to scramble the data before transmission by the multilane data transmitter. A first data scrambler is configured to scramble data starting with a first seed signal specifying an initial state of the first data scrambler. A second data scrambler is configured to scramble data starting with a second seed signal specifying an initial state of the second data scrambler. The first seed signal and the second seed signal differ from each other by a predetermined signal distance measure that increases the randomness among the data from the set of data scramblers.
