Abstract
An up/down detection unit samples a received data signal and determines in which of first through third areas of the data signal the logic level of the data signal transitions, wherein the data sampling clock signal, the first edge sampling clock signal, and the second edge sampling clock signal are sequentially activated. A lower limit detection unit detects a lower limit of the first area if the logic level of the data signal transitions in the first area. An upper limit detection unit detects an upper limit of the third area if the logic level of the data signal transitions in the third area. A phase detection unit determines a delay amount indicating the amount by which the data signal is to be delayed according to the upper limit and lower limit detected. A buffer unit delays the data signal by the delay amount determined by the phase detection unit.
