Abstract
A method and apparatus utilizing a data processing system are disclosed for multi-level data communication providing self-clocking. A first digital signal is input which includes a series of digital bits. One of a plurality of output levels is associated with each group of data bits for each of the plurality of the digital bits included within the first digital signal. A particular output level is associated with a clock output level. An output signal is generate which includes a transmission of the output level for each of the groups of digital bits and includes multiple transmissions of the clock output level, where a clock output level is transmitted after each transmission of an output level for each of the groups of digital bits.
