Classification: CPC H | IPC H

Claim 8:
9. The reception device according to claim 1, wherein
the equalizer circuit includes a first equalizer circuit and a second equalizer circuit,
the first equalizer circuit is configured to output the output value at each even-numbered clock timing,
the second equalizer circuit is configured to output the output value at each odd-numbered clock timing, and
the control circuit is configured to:
before the data signal is received,
detect a first inverted tap coefficient that is the tap coefficient at the boundary where the data value of the output value is inverted by changing the tap coefficient in a state in which the second voltage, instead of the voltage of the data signal, is supplied to the first equalizer circuit;
detect a second inverted tap coefficient that is the tap coefficient at the boundary where the data value of the output value is inverted by changing the tap coefficient in a state in which the second voltage, instead of the voltage of the data signal, is supplied to the second equalizer circuit;

at the time of receiving the data signal,
set the first inverted tap coefficient to the first equalizer circuit; and
set the second inverted tap coefficient to the second equalizer circuit.
