SIGNAL TRANSMISSION DEVICE, SIGNAL TRANSMISSION SYSTEM, SIGNAL TRANSMISSION METHOD, AND COMPUTER DEVICE

摘要

A signal transmission device includes a differential driver, a first single-ended driver circuit block, a second single-ended driver circuit block, a control circuit, and a common-mode filter. In the case where two-channel single-ended transmission is performed by using the first and second single-ended driver circuit blocks, the control circuit controls a driving capability of the first single-ended driver circuit block and a driving capability of the second single-ended driver circuit block in accordance with a combination of a change in a logical value of an output signal of the first single-ended driver circuit block and a change in a logical value of an output signal of the second single-ended driver circuit block.
