Abstract:
A data transmission apparatus comprising:a transmitting device;a receiving device; anda data transmission line for transmitting a data signal from said transmitting device to said receiving device,wherein said transmitting device has a signal circuit which outputs a first signal having a specific relation in phase to said data signal,wherein said first signal is sent from said transmitting device to said receiving device over a signal transmission line, said data transmission line and said signal transmission line being devised so that phase differences between said data signal and said first signal fall within a predetermined range, andwherein said receiving device comprises:a plurality of registers which receive a second data signal in response to a clock signal of said receiving device,a determination circuit which determines relations between said clock signal and said first signal, anda phase adjustment circuit which adjusts said data signal in phase based on said relations determined by said determination circuit and outputs the adjusted signal as said second data signal.
