Abstract: A data receiver, which communicates with a data transmitter through a plurality of lanes, includes: a first reception unit which receives first data through a first lane; a second reception unit which receives second data through a second lane; and a detector which compares the first data and the second data to detect a skew between the first lane and the second lane. The first reception unit includes a first clock data recovery unit which recovers a first clock and first payload data from the first data. The first reception unit controls a loop speed of the first clock data recovery unit based on a skew level of the skew.

Abstract: A transceiver includes a transmitter and a receiver connected to each other through a first line and a second line. The transmitter transmits signals having a first voltage range to the first line and the second line in a first mode, and transmits signals having a second voltage range less than the first voltage range to the first line and the second line in a second mode. In transmitting a (1−1)-th payload to the receiver, the transmitter is sequentially driven in the first mode, the second mode, and the first mode, and transmits a first clock training pattern and the (1−1)-th payload in the second mode. The receiver includes a clock data recovery circuit generating a first clock signal corresponding to the received first clock training pattern and a register storing first frequency information and first phase information of the first clock training pattern.
