The serial data transmission system of the present invention employs at least three transmission lines (LINE 0, LINE 1, LINE 2, LINE 3) for transmitting the serial data. Each of the transmission lines can be designated as the data line D or as a strobe line S. Circuits (SHIFT REGISTER 20, XOR 8) are provided for dynamically designating, for each binary data bit transmission period, one transmission line as the data line D and one transmission line as the strobe line S such that two successive data transitions will not occur on any transmission line. In each binary data bit transmission period, an encoder (fig. 1) will cause a transition to occur on either the data line D or on strobe line S as a function of the value of the data bit to be transmitted by that data period. At the receiving station (fig. 2), circuits are provided for determining if a transition occurred, during the data bit transmission period, on either the transmission line designated as data line D or the transmission line designated as strobe line S for that data bit transmission period. Further circuits are provided for determining the next data bit transmission period which of the transmission lines will be designated as the data line D and which of the transmission lines will be designated as the strobe line S. Data decoder (SHIFT REGISTER 85) is provided for recovering the binary data encoded by the encoder (fig. 1). |
