Patent ID: 7983347

Claim:
A signal transmitter for use in a multiple differential transmission system including the signal transmitter, a signal receiver, and a signal transmission path, the signal transmission path including first, second, and third signal lines for connecting the signal transmitter to the signal receiver, the signal transmitter comprising: a first differential driver for transmitting a first output signal and an inverted first output signal that is a phase-inverted signal with respect to the first output signal, in response to a first bit information signal; a second differential driver for transmitting a second output signal and an inverted second output signal that is a phase-inverted signal with respect to the second output signal, in response to a second bit information signal; and a third differential driver for transmitting a third output signal and an inverted third output signal that is a phase-inverted signal with respect to the third output signal, in response to a third bit information signal; wherein the signal transmitter combines the first output signal and the inverted third output signal, and transmits a resulting combined signal to the first signal line, wherein the signal transmitter combines the second output signal and the inverted first output signal, and transmits a resulting combined signal to the second signal line, wherein the signal transmitter combines the third output signal and the inverted second output signal, and transmits a resulting combined signal to the third signal line, wherein an absolute value of binary signal voltages of the first output signal is set to be the same as an absolute value of binary signal voltages of the second output signal, and wherein an absolute value of binary signal voltages of the third output signal is set to be different from an absolute value of binary signal voltages of the first output signal.
