ABSTRACT:
A method of transmitting and receiving a differential self-clocking data stream. The communications link comprises the coding of information signals onto two signal wires using two logic levels on each wire for a total of four possible coding symbols. The four symbols are utilized to encode data and control-states in both electrically differential and common mode manner upon the two signal wires. The coding sequence is chosen so as to facilitate the communications of binary data and control signals along with demarcation of each successive bit boundary by utilizing the consecutive symbol sequences which are nonrepetitive.
