Abstract: A transceiver includes a transmitter and a receiver which are connected to each other through a first line and a second line. The transmitter transmits a first clock training pattern to the receiver in a first period, transmits a second clock training pattern and a first first payload to the receiver in a second period, and transmits a third clock training pattern and a second first payload to the receiver in a third period. The first clock training pattern, the second clock training pattern, and the third clock training pattern are variable based on a plurality of driving modes.

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 includes a transmitter and a receiver connected to each other by 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 smaller than the first voltage range to the first line and the second line in a second mode. The transmitter encodes an original payload in the second mode to generate a first payload, and transmits the clock training pattern and the first payload through the first line and the second line.

Abstract: A digital-analog converter of the disclosure converts digital image data to generate analog data signals. The digital-analog converter includes a voltage divider which generates a plurality of gamma reference voltages based on a first reference voltage and a second reference voltage; a global ramp including a plurality of gamma decoders which generates a plurality of global gamma voltages based on the gamma reference voltages; a decoder which selects one of the global gamma voltages according to the digital image data to generate the analog data signals; and a ramp controller which turns off at least some of the gamma decoders based on the digital image data.
