In the case of mounting two serial communication interfaces such as PCI-e and USB 3.0 with standards different from each other, it is allowed to flexibly address a design change and the like, and reduce a board area. An interface device includes a PCI-e I/F, a USB 3.0 I/F with characteristic impedance and an electric characteristic which are equivalent to those of the PCI-e I/F, and a controller provided with the PCI-e I/F and the USB 3.0 I/F. The interface device is provided with a PHY bus switch for selectively switching between the PCI-e I/F and the USB 3.0 I/F, and in which wiring for connecting the PCI-e I/F and the PHY bus switch and wiring for connecting the USB 3.0 I/F and the PHY bus switch are shared therebetween. |
