| 1. A data receiver in which waveforms of data signals are shaped, comprising:
a plurality of reception circuits each of which receives a data signal through a transmission line, and includes an equalizer
having a function of performing waveform shaping of the data signal;
an equalizer adapter which is arranged in correspondence with all or every predetermined number of ones of the plurality of
reception circuits, and calculates equalization coefficients for the equalizer in each of the plurality of reception circuits
corresponding to the equalizer adapter based on data from each of the plurality of reception circuits, where the predetermined
number is two or greater; and
a timing absorption unit which absorbs a difference between a first time at which each of the plurality of reception circuits
outputs the data and a second time at which the equalizer adapter receives data.
