Abstract
A serial data transmission system employing at least three transmission lines for transmitting the serial data. Each of the transmission lines can be designated as a data line 1 or as a data line 2. An encoder dynamically designates, for each binary data bit transmission period, one transmission line as data line 1 and one transmission line as data line 2 such that the transitions representing two data bits being transmitted in two successive transmission periods not occur on any one of the transmission lines. In each binary data bit transmission period, the encoder will cause a transition to occur on either data line 1 or data line 2 as a function of the value of the data bit to be transmitted during that transmission period. A decoder retrieves the data bit for each transmission period in accordance with whether the transition occurred on the transmission line designated as data line 1 or the transmission line designated as data line 2 for that period and determines for the next transmission period which of the transmission lines will be designated as the data line 1 and which of the transmission lines will be designated as the data line 2.
