Abstract:
1. A transmission characteristic adjustment device that adjusts a transmission characteristic between a transmission element and a reception element with a transmission path interposed therebetween, the device comprising: a determination section that determines existence or non-existence of a difference with respect to confirmed data based on each phase of a multiphase clock; a window detection section that detects a window width in a time axis direction of receiving data based on a result of determination of the determination section and a phase of the multiphase clock; and a circuit element setting section that 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 window width detected by the window detection section, and changes the setting value of the circuit element of the transmission element or the reception element based on a result of the evaluation.
