摘要
A deskew system includes a first voltage control delay receiving a data signal and generating N-numbered delayed data signals obtained by delaying a phase of the data signal in units of 90/N, where N is a natural number that is not less than 1. In response to a phase control signal, a second voltage control delay receives a clock and generates N-numbered delayed clocks by delaying a phase of the clock in units of 90/N. A skew compensation control unit generates a plurality of skew control signals to compensate for skew between the data signal and the clock based on the data signal, the N-numbered delayed data signals, the clock, and the N-numbered delayed clocks.
