Abstract

In a data transmitter, a main line driver circuit transmits an input signal to a receiver via a channel. A pre-emphasis circuit emphasizes a voltage level of the transmitted input signal, and a pre-emphasis controller controls the pre-emphasis circuit. The pre-emphasis controller adjusts a pre-emphasis level of the pre-emphasis circuit to increase an amount of current supplied to the channel at a transition time of the input signal in accordance with the transition condition of the channel.
