<p><P>PROBLEM TO BE SOLVED: To solve such a problem that it takes time to adjust intensity adjustment values in a receiver circuit including an equalizer circuit for adjusting the intensity of reception signals. <P>SOLUTION: The receiver circuit includes: an equalizer circuit 10 for adjusting reception intensity of an input signal based on an intensity adjustment value; a first holding unit 20 for holding two or more pieces of data sampled based on a sampling clock CLK.data in a receiving order; a second holding unit 30 for holding a plurality of boundary values of the data sampled based on a complementary sampling clock CLK.Edge in a receiving order; and an equalizer control circuit 50 for determining the strength of reception intensity of a correction input signal Data.Eq based on output signals of the first holding unit 20 and output signals of the second holding unit 30 to update the intensity adjustment value. The equalizer control circuit 50 determines the strength of the reception intensity based on a plurality of values held in the second holding unit 20 when first data Data0 and second data Data1 indicate the same polarity. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
