Abstract
A receiver circuit includes an equalizer circuit that adjusts reception intensity of an input signal based on an intensity adjustment value to generate a correction input signal; a first holding unit that holds a plurality of data items sampled based on a sampling clock for sampling values of the data items transmitted by the correction input signal in a receiving order; a second holding unit that holds a plurality of values of the correction input signal sampled based on a complementary sampling clock for sampling a boundary value of the data items in a receiving order; and an equalizer control circuit that judges the strength of reception intensity of the correction input signal based on a plurality of output signals of the first holding unit and a plurality of output signals of the second holding unit to update the intensity adjustment value based on the judgment result.
