    摘要： In a multi-wire channel that includes at least three wires, each unique wire pair of the multi-wire channel has approximately the same signal propagation time. In this way, jitter can be mitigated in the multi-wire channel for signaling where, for a given data transfer, a differential signal is transmitting on a particular pair of the wires and every other wire is floating. In some implementations, matching of the signal propagation times involves providing additional delay for at least one of the wires. The additional delay is provided using passive signal delay techniques and/or active signal delay techniques.

    摘要： System, methods and apparatus are described that facilitate transmission of data, particularly between two devices within electronic equipment. Transmission lines are selectively terminated in an N-phase polarity encoded transmitter when the transmission lines would otherwise be undriven. Data is mapped to a sequence of symbols to be transmitted on a plurality of wires. The sequence of symbols is encoded in three signals. Each of the three terminals may be driven such that transistors are activated to couple a terminal to first and second voltage levels through a pair of impedances when the terminal would otherwise be undriven. The terminal is then pulled toward an intermediate voltage level while the terminal presents a desired impedance level to a transmission line.

    摘要： System, methods and apparatus are described that facilitate transmission of data, particularly between two devices within an electronic apparatus. Data is selectively transmitted as
    N -phase polarity encoded symbols or as packets on differentially driven connectors. A desired operational mode for communicating between the two devices is determined, an encoder is selected to drive a plurality of connectors communicatively coupling the two devices, and a plurality of drivers is configured to receive encoded data from the encoder and drive the plurality of connectors. Switches may couple outputs of the selected encoder to the plurality of drivers. One or more outputs of another encoder may be caused or forced to enter a high impedance mode.
