Abstract
First and second transmission lines and are connected to each other in series. A first terminator is connected to the first transmission line in parallel, and is provided externally of a semiconductor device. A second terminator is connected to the second transmission line in parallel, and is provided inside the semiconductor device. The values of the first and second terminator are adjusted so that the combined resistance value of first and second terminator and the second transmission line matches with the impedance of the first transmission line. Impedance matching of the entire transmission line can be achieved with this simple construction, thus, a stable, high quality signal can be transmitted.
