1. A system comprising:

  • a single-ended transmission line;

    a pair of differential transmission lines;

    a transmitter outputting a single-ended signal to the single-ended transmission line and a pair of differential signals to the pair of differential transmission lines;

    a receiver receiving the single-ended signal via the single-ended transmission line and the pair of differential signals via the pair of differential transmission lines;

    a first termination voltage applied to one of the pair of differential transmission lines;

    a second termination voltage applied to the other differential transmission line; and

    a third termination voltage applied to the single-ended transmission line;

    a first termination resistor, one end of which is connected to one of the pair of differential transmission lines;

    a second termination resistor, one end of which is connected to the other of the pair of differential transmission lines;

    a third termination resistor, one end of which is connected to the single-ended transmission line,wherein the first termination voltage is different from the second termination voltage, and the third termination voltage is half a power supply voltage applied to the transmitter, andwherein the resistance values of the first termination resistor, the second termination resistor and the third termination resistor are substantially equivalent.
