<P>PROBLEM TO BE SOLVED: To provide a signal transmission circuit and a signal transmitting method which compensates the phase difference between a plurality of data signals transferred between chips. <P>SOLUTION: The signal transmission circuit comprises output terminals 101-103 for outputting data signals, a first to third delays 11-13 for delaying the phases of the data signals outputted from the plurality of output terminals, a delay value setting unit 14 for setting the delay values to the first to third delays 11-13, a phase difference detector 15 for measuring the phase differences between the data signals outputted from the first to third delays 11-13 to output phase difference information, and a calculator 16 for calculating the compensation values for the delay values used when the first to third delays 11-13 delay the phases of the data signals, based on the phase difference information. The delay value setting unit 14 compensates the delay values of the first to third delays 11-13, based on the compensation values. <P>COPYRIGHT: (C)2008,JPO&INPIT |
