2. A system, comprising: an interconnect fabricated on an interposer device; an integrated circuit die coupled to the interposer device, the integrated circuit die fabricated to include: a data transmitter circuit, configured to: receive an input data word for transmission, wherein the input data word includes two or more independent bits of digital data; encode the input data word into a code word; and drive the code word on to the interconnect for transmission, wherein the interconnect includes signal wires corresponding to bits comprising the code word; and a data receiver circuit fabricated within a different integrated circuit die and coupled to the interposer device, wherein the data receiver circuit is configured to decode the code word to generate an output data word that is equivalent to the input data word.
3. The system of claim 2 , wherein the code word exhibits an equal number of low-going and high-going transitions for an arbitrary code word transition.
