<P>PROBLEM TO BE SOLVED: To make it possible to mount a transmitting unit and a receiving unit onto different faces of a board by using each IC with the same terminal location while maintaining a transmission path in parallel and with equal lengths in differential transmission method. <P>SOLUTION: The differential transmission circuit includes a transmission unit for generating a pair of differential signals from an input signal and transmitting them, a receiving unit for receiving the differential signal transmitted from the transmitting unit, and a transmission path for transmitting the differential signal from the transmitting unit to the receiving unit. The transmission unit has a selection unit for selecting the input signal or a signal with polarity reversed to that of the input signal, and a differential signal is generated from the signal selected by the selection unit. <P>COPYRIGHT: (C)2010,JPO&INPIT |
