Abstract: A transceiver includes a transmitter and a receiver coupled to each other through a first line and a second line. The transmitter transmits a first voltage signal of a second logic level or a fourth logic level, among a first logic level, the second logic level, a third logic level, and the fourth logic level, through the first line. The transmitter transmits a second voltage signal of the first logic level or the third logic level through the second line. The receiver generates an output signal having one of four values based on the first voltage signal and the second voltage signal.

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. When transmitting a first payload to the receiver, the transmitter is sequentially driven in the first mode, the second mode, and the first mode, and the transmitter transmits a clock training pattern and the first payload in the second mode.

Abstract: A transmitter includes a transmission controller which outputs original data through an original data lane, an encoder which encodes the original data into encoded data and outputs the encoded data through an encoded data lane, and a transmission driver which outputs the encoded data at a speed of M (M is a real number greater than 0) gigabits per second through a transmission and reception interface. The transmission driver provides a first clock signal corresponding to an output speed to the encoder, the encoder provides a second clock signal having a second frequency less than a first frequency of the first clock signal to the transmission controller, the transmission controller outputs the original data based on the second clock signal, and the encoder outputs the encoded data based on the first clock signal.

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.

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 by a first line and a second line. The transmitter transmits signals each having a first voltage range to the first line and the second line in a first mode, and signals each having a second voltage range less than the first voltage range to the first line and the second line in a second mode. The receiver includes a low-power driver which receives signals through the first line and the second line in an operating state of the first mode, and stops an operation thereof in the second mode, and a high-speed driver which receives signals through the first line and the second line in the second mode, and stops an operation thereof in the first mode.
