Abstract
An apparatus and method for transmitting an 8-bit binary format data word as a 6-trit ternary code word includes an encoder, a decoder, and a code assignment that produce, for each 8-bit data word value, an unique 6-trit ternary code word that is particularly optimized for transmission over twisted-pair cable. The logic circuitry of the invention is optimized to accomplish the translation using a small number of combinatorial logic gates. The present invention thus has advantages in size, speed and performance over other possible means for encoding an 8 bit data word to a 6 trit code word.
