Differential transmission circuit |
摘要 |
A differential transmission circuit comprises a sending unit that generates a pair of differential signals from an input signal, and sends the differential signals; a receiver that receives the differential signals sent by the sending unit; and a transmission path that transmits the differential signals from the sending unit to the receiver, wherein the sending unit has a selector that selects one of the input signal and a signal obtained by inverting a polarity of the input signal, and generates the differential signals from the signal selected by the selector. |

1. A differential transmission circuit which comprises a terminal from which an input signal is input, terminals to which a pair of differential signals generated from the input signal are output, and a terminal to which an output signal generated from the differential signals is output, wherein the input signal comprises a first input signal and a second input signal, and the differential signals comprise first differential signals and second differential signals, the differential transmission circuit comprising:
a first selector that selects one of the first input signal and a signal obtained by inverting a polarity of the first input signal; a second selector that selects one of the second input signal and a signal obtained by inverting a polarity of the second input signal; a third selector that selects, as a third signal, one of the signal selected by the first selector and the signal selected by the second selector; a fourth selector that selects, as a fourth signal, one of the signal selected by the first selector and the signal selected by the second selector; and a generating unit that generates the first differential signal from the third signal and generates the second differential signals from the fourth signal. |
