description | A data reception device includes: an equalizer circuit that shapes a waveform of an input signal according to a set gain value; a CDR circuit which recovers a plurality of clock signals having different phases in one cycle from the input signal after being subjected to the waveform shaping performed by the equalizer circuit; an oversampler which performs sampling of the waveform-shaped input signal in synchronization with the plurality of clock signals and recovers a plurality of input data from the waveform-shaped input signal; and a calibration control unit which determines whether the oversampler correctly recovers the input data based on a result of the sampling performed by the oversampler, and generates a control signal to set the gain value of the equalizer circuit based on a determination result when it is determined that the input data is not correctly recovered. |
