PROBLEM TO BE SOLVED: To provide a method and a system for preventing the amplitude reduction of a clock signal which causes the limit of a transmission distance in cable transmission and reducing radiation noise. SOLUTION: In the case of transmitting clock, data and frame signals through a cable in parallel, serial data are converted into N parallel data, the frequency of a clock is divided into 1/N and parallel data and a frame of which physical speed is dropped to 1/N correspondingly to N are transmitted/received on the cable. The signal transmitting side is provided with a parallel number specification part 5 for specifying N, a serial/parallel(S/P) conversion part 4 for converting serial data into parallel data and a clock frequency dividing part for dividing the frequency of a clock into 1/N frequency and the signal receiving side is provided with a parallel number specification part for specifying N, a P/S conversion part for converting parallel data into serial data and a clock multiplying part. |
