摘要：
A comparison period detecting unit (11) defines, as a comparison period, a period between a rising edge of a first clock signal and a rising edge of a second clock signal, and detects the presence or absence of transition of a data signal during the comparison period. A phase relationship detecting unit (12) detects a phase relationship between the data signal and a reference clock signal, and outputs a result of detection of the phase relationship when the comparison period detecting unit (11) detects transition of the data signal during the comparison period.
