PURPOSE: A transmitter for data communication is provided to execute pre-emphasis by determining an optimal pre-emphasis degree by modeling a channel. CONSTITUTION: A serialization device(110) converts data inputted to an input end into serial data. A pre-output driver(120) generates pre-emphasis data by firstly emphasizing the serial data. An output driver(130) generates output data by receiving the pre-emphasis data. The output driver secondly emphasizes the pre-emphasis data by controlling a delay value. A pre-output controller(140) controls the delay value of the delay data applied to the pre-emphasis of an output driver by implementing the situation of a channel. A variable capacitor is installed between the pre-output controller and an output driver. The variable capacitor controls the capacitance according to the delay value. |
