A Transceiver using Mode-Division-Multiplex-Transmission method for a Single-Ended Cable

This paper describes a transceiver of semiconductor Integrated Circuit (IC) to implement a mode-division-multiplex-transmission method for high-speed and single-ended signaling through a shielded multi-wire cable. Usually, single-ended digital data transmission over long multiwire cables makes it difficult to achieve high bandwidth data communication because crosstalk between wires in the cable degrades the data eye opening of each wire. The proposed method can significantly reduce crosstalk in principle by assigning eigenmodes to wires in the cable. The transceiver can transmit and receive multi-level digital data that conforms to the proposed method. Appropriate eye openings were verified in actual measurements using the transceiver and cable, demonstrating the reliability and effectiveness of this method.
