A reception device for receiving a data signal representing a data value 0 or 1. The reception device includes an equalizer circuit and a control circuit. The equalizer circuit outputs an output value representing a result obtained by comparing a voltage based on the received data signal and a first voltage as a reference, at each clock timing corresponding to the data signal.

The control circuit sets the inverted tap coefficient to the equalizer circuit at a time of receiving the data signal.
