Techniques for increasing randomness among the communication lanes of a multilane wired data communication link

An apparatus for increasing randomness among different communication lanes of a multilane wired data communication link, the apparatus comprising:

• a multilane data transmitter configured to simultaneously transmit data over a first communication lane of the multilane wired data communication link and a second communication lane of the multilane wired data communication link;
• and
• a set of data scramblers configured to scramble the data before transmission by the multilane data transmitter, wherein a first data scrambler of the set of data scramblers is assigned to scramble data for transmission over the first communication lane and a second data scrambler of the set of data scramblers is assigned to scramble data for transmission over the second communication lane;
• wherein the first data scrambler is configured to scramble data starting with a first seed signal specifying an initial state of the first data scrambler,
• wherein the second data scrambler is configured to scramble data starting with a second seed signal specifying an initial state of the second data scrambler,
• wherein 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.
