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: An indoor unit of an air conditioner includes a frame of the indoor unit; a heat exchanger mounted on the frame and having a refrigerant pipe in which a refrigerant flows; a hanger plate mounted on a rear surface of the frame and configured to fix the frame onto a wall surface; and a holder plate mounted on a lower portion of the frame and connecting the frame and the hanger plate. An end of the refrigerant pipe is placed in a space formed by the frame, the holder plate, and the hanger plate. The holder plate is movably connected on a lower portion of the frame, so the refrigerant pipe is accessible to a user to perform an operation of connecting or separating the refrigerant pipe to or from a connection pipe connected to an outdoor unit without rotating the frame.

Abstract: An indoor unit of an air conditioner having an improved frame structure in which a refrigerant pipe that connects an outdoor unit and the indoor unit can be easily connected. The indoor unit of the air conditioner includes: a frame; a heat exchanger mounted on the frame and having a refrigerant pipe in which a refrigerant flows; a hanger plate mounted on a rear surface of the frame and fixing the frame onto a wall surface; and a holder plate mounted on a lower portion of the frame, fixing the frame and the hanger plate, and supported by a fixing member of the wall surface. The holder plate selectively opens/closes the lower portion of the frame so that a pipe connection operation can be easily performed.

Abstract: An air conditioner includes an outdoor unit that includes a compressor configured to compress a refrigerant, a condenser configured to condense the compressed refrigerant, and a blowing fan configured to blow outdoor air into a room, an indoor unit that discharges air heat-exchanged with the refrigerant flowing-in from the outdoor unit to the room, and a connection piping that connects the outdoor unit and the indoor unit. Here, a plurality of protrusions may be formed at least one side of the blowing fan, and a convex portion and a concave portion may be formed on a surface of the blowing fan so that the surface of the blowing fan is indented.
