Abstract
A method for transmitting data advantageously reduces cross-talk in high-speed data transmission. The method comprises receiving an input data word, encoding the input data word into a code word, and driving the code word on to an interconnect for transmission. The code word is generating using a balanced coding scheme, and the interconnect is a single-ended, twisted-wire interposer interconnect. A receiver circuit decodes the code word to generate an output data word.
Claims17
A method, comprising:
- receiving an input data word for transmission by a data transmitter circuit disposed within an integrated circuit die, wherein the input data word includes two or more independent bits of digital data;
- encoding the input data word into a code word by the data transmitter circuit;
- driving the code word on to an interconnect for transmission by the data transmitter circuit, wherein the interconnect is a single-ended, twisted-wire interconnect fabricated on an interposer, the interconnect is coupled to the integrated circuit die, and the interconnect includes signal wires corresponding to bits comprising the code word;
- and
- receiving the code word that is transmitted through the interconnect by 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.
