Transceiver device, display system including the same, and method of driving transceiver device

A method of driving a transceiver device including a transmitter and a receiver connected to each other through a first line and a second line, the method comprising:

• transmitting signals having a first voltage range from the transmitter to the receiver in a first mode;
• and
• transmitting signals having a second voltage range, which is less than the first voltage range, from the transmitter to the receiver in a second mode,
• wherein the transmitting the signals having the second voltage range comprises:
• transmitting a clock training pattern from the transmitter to the receiver through the first line and the second line;
• generating a first payload by encoding an original payload using an encoder included in the transmitter, and transmitting the first payload from the transmitter to the receiver through the first line and the second line;
• generating an RX clock signal of the receiver based on the clock training pattern and the first payload;
• and
• providing reception data corresponding to the original payload by decoding the first payload using a decoder included in the receiver,
• wherein the providing the reception data comprises:
• inputting the first payload to the decoder in synchronization with each active level of a clock period of the RX clock signal, and
• outputting the reception data from the decoder in synchronization with each active level of a clock period of an RX byte clock signal, which is generated by masking a portion of the RX clock signal.

A display system comprising:

• a processor which outputs image data;
• a display module which displays an image based on the image data;
• and
• a transceiver device which is in charge of data transmission and reception between the processor and the display module,
• wherein the transceiver device comprises 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,
• the transmitter encodes an original payload to generate a first payload in the second mode, and transmits a clock training pattern and the first payload through the first line and the second line,
• the receiver comprises a decoder which decodes the first payload to output reception data corresponding to the original payload in the second mode,
• the receiver generates an RX clock signal based on the clock training pattern and the first payload,
• the first payload is input to the decoder in synchronization with each active level of a clock period of the RX clock signal, and
• the reception data is output from the decoder in synchronization with each active level of a clock period of an RX byte clock signal, which is generated by masking a portion of the RX clock signal.
