Abstract:
1. A signal transmission device, comprising: a differential signal transmission unit operable to output a differential signal to a pair of signal lines including a first signal line and a second signal line, the differential signal transmission unit having two output terminals; a single-ended signal transmission unit operable to output mutually independent two-channel single-ended signals to the first signal line and the second signal line respectively, the single-ended signal transmission unit having two output terminals; and a filter unit including a first common mode filter and a second common mode filter, wherein: one of the output terminals of the differential signal transmission unit and one of the output terminals of the single-ended signal transmission unit are connected to the first signal line via one of two inductors of the first common mode filter of the filter unit; and the other one of the output terminals of the differential signal transmission unit and the other one of the output terminals of the single-ended signal transmission unit are connected to the second signal line via one of two inductors of the second common mode filter of the filter unit.
