Abstract
A method and an apparatus for enabling a data signal to be transmitted stably at high speed over long distances without using thicker cables and without increasing physical quantities of such resources as transmitting-receiving circuit elements are disclosed. On the transmitting side, the phase of a clock signal relative to the data signal is modified in accordance with the distance between the transmitting and the receiving sides, the clock signal being transmitted along with the data signal. On the receiving side, the incoming data signal is received in synchronism with the received clock signal.
