Abstract
A data reception device includes a reference clock generation unit including a first DCDL, a phase detection circuit, and a digital loop filter, and receiving an input clock signal CK0 and outputting the input clock signal and a first phase clock signal CK90 having a phase difference of 90 degrees with respect to the input clock signal; and a data sampling unit including a second DCDL that receives a data signal DI, the input clock signal, and the first phase clock signal, and delays the data signal, and sampling and outputting a data value of the data signal at an edge of the input clock signal, thereby remarkably reducing an amount of power consumption used for skew correction.
