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.
