Data reception apparatus

A data reception apparatus is disclosed. The data reception apparatus includes a strobe extractor for receiving a transmission signal and extracting a strobe signal from the transmission signal, the transmission signal including the strobe signal inserted between data signals and a clock signal following the strobe signal, the strobe signal having a different magnitude from a magnitude of a data signal, and the clock signal having an equal magnitude to the magnitude of the data signal, a clock recoverer for recovering the clock signal from the transmission signal, using the extracted strobe signal, and a sampler for sampling the data signals included in the transmission signal in response to the recovered clock signal. The probability of generating a timing skew error in the time interval between a clock signal and a data signal is minimized. Even though the level of a common component might change, the clock signal can be recovered accurately and the size of the clock recovery circuit can be reduced. Further, the data reception apparatus is suitable for transmitting/receiving data at a high transmission rate, and is robust against noise generated during transmission of the data signal and the clock signal, or against noise generated along a common path.
