ABSTRACT:
Binary encoded information having a word size of 3N bits, where "N" is a positive integer, plus a parallel data clock are converted to corresponding control signals. Signal drivers with three-state outputs respond to the control signals and communicate corresponding signals via transmission lines, one transmission line per signal driver, to receiving circuits capable of detecting three-state signals, an embodiment of said circuits produce bipolar signals corresponding to the state of the transmission lines with which they communicate. A code converter produces binary signals and a data clock corresponding to the bipolar signals from the receiving circuits. The net result is that the binary word and data clock produced at a receiving end of the transmission lines logically matches the binary code and data clock applied at a sendng end, and that the produced data clock has the same timing relationship with the received binary word as does the originating data clock have with the originating binary word.
