Abstract
The present invention relates to a digital data transceiver circuit applicable to a flat panel display such as an LCD to be placed between graphic signal generation module and liquid crystal display module or between timing control IC and data driver IC, etc. A digital data transceiver circuit of the present invention has a first current source and a second current source, and the second current source is controlled to supply a current or not depending on the status of the lower bit of input data. A transmitter is connected to a node, on which the first and second current sources combine, and the transmission paths of currents from the two current sources are determined depending on the status of the upper bit of input data. A signal of the transmitter is transmitted through a transmission line, and a termination resistor is connected to the transmission line. A receiver detects output data according to a voltage applied to the termination resistor. The digital data transceiver circuit of the present invention can transmit 2-bit or 3-bit data during one clock period, and it is resistible to the noise better than the voltage transmission method and effective to long distance transmission.
