    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.

    摘要: An output circuit (12) converts a pair of current signals supplied to a pair of common nodes (NCa and NCb) into a pair of voltage signals (VOa and VOb). In each of input buffer circuits (11, 11, . . . ), a constant current generation section (101) generates, in an output mode, a pair of constant currents in a pair of current paths going from a pair of intermediate nodes (NMa and NMb) to a reference node (VDD1), and stops the generation of the pair of constant currents in a cutoff mode. A voltage-to-current conversion section (102) generates, in the output mode, a pair of input currents corresponding to a pair of input signals (Sa and Sb) in a pair of current paths going from the pair of intermediate nodes (NMa and NMb) to a reference node (GND) to thereby generate a pair of current signals (Ia and Ib) in a pair of current paths going from the pair of intermediate nodes (NMa and NMb) to the pair of common nodes (NCa and NCb), and stops the generation of the pair of input currents in the cutoff mode.
