According to an aspect of the embodiment, a driver outputs a driver current to a reception LSI, and a receiver included in the reception LSI receives an analog voltage signal corresponding to a value of the driver current as a receiver input. An A/D converter converts the voltage signal of the receiver input to a digital value, and transmits the digital value to a driver current controller in a transmission LSI. The driver current controller adjusts a number of PMOS driving stages in the driver or a number of NMOS driving stages in the driver, to make the digital value of the voltage signal of the receiver input belong to a predetermined range.
