A High-speed IEEE 1394 Link Interface is disclosed. Also disclosed is an interface device and method that is compatible with legacy IEEE 1394 devices. The device is used to replace a conventional 1394 physical layer interface device and can then cooperatively operate with a slightly modified link layer controller. The device is further selectively activatable and deactivatable. When activated, the device will double the clock speed, and therefore permit data transfer rates of 1600 Megabits per second, with Control Signal transfer speeds of 200 MHz.
