description 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 is connected to the equalizer circuit. The control circuit changes, before the data signal is received, a tap coefficient related to a characteristic of the equalizer circuit in a state in which a second voltage different from the first voltage, instead of the voltage of the data signal, is supplied to the equalizer circuit, to detect an inverted tap coefficient that is the tap coefficient at a boundary where a data value of the output value is inverted. The control circuit sets the inverted tap coefficient to the equalizer circuit at a time of receiving the data signal.
