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.

Abstract: A transceiver device includes a transmitter and a receiver connected through first and second lines. A first frame period includes an active period for transmitting a first payload and a vertical blank period including a frequency hopping period. The transmitter transmits, to the first and second lines, signals having a first voltage range in a first mode and signals having a second voltage range in a second mode. The transmitter generates a first horizontal synchronization signal in the second mode except for the frequency hopping period, encodes the first horizontal synchronization signal to horizontal synchronization data, and generates a second horizontal synchronization signal in the first mode in the frequency hopping period. The transmitter adds a first clock training pattern to the horizontal synchronization data except for the frequency hopping period, and adds a second clock training pattern to first horizontal synchronization data after the frequency hopping period.
