<P>PROBLEM TO BE SOLVED: To provide a receiving circuit capable of accurately detecting a signal pattern of a data signal on a reception side. <P>SOLUTION: The receiving circuit 12 receives a first data signal S<SB>DATA</SB>and a reference signal S<SB>FIX</SB>used to set a clamp voltage for clamping a detection signal for detecting the first data signal. The receiving circuit 12 includes an amplitude investigation circuit 13 which detects an H-level voltage and an L-level voltage of the reference signal S<SB>FIX</SB>, a clamp circuit 14 which clamps an H-level voltage and an L-level voltage of the detection signal to the clamp voltage, a control circuit 15 which sets the clamp voltage for the clamp circuit 14 based upon the H-level voltage and L-level voltage of the reference signal detected by the amplitude investigation circuit 13, and a data signal generation circuit which generates a second data signal based upon the detection signal clamped by the clamp circuit 14. <P>COPYRIGHT: (C)2011,JPO&INPIT |
