ABSTRACT:
A transmission characteristic adjustment device and the like that can carry out circuit adjustment before an error occurs, and has a transmission characteristic with high reliability without generating an error are provided.The device determines existence or non-existence of a difference with respect to confirmed data based on each phase of a multiphase clock, detects a window width in a time axis direction of receiving data based on a result of the determination and a phase of the multiphase clock, and evaluates a setting value of a circuit element of the transmission element or the reception element that has an influence on a receiving waveform based on a fluctuation of the detected window width, and changes the setting value of the circuit element of the transmission element or the reception element based on a result of the evaluation.
