Abstract
A chip is provided with a specific signal wire and two adjacent signal wires. Output signals based on a specific signal and two adjacent signals are transmitted to the specific signal wire and the two adjacent signal wires respectively. An adjustment coefficient is stored in a memory. The adjustment coefficient is used for reducing an occurrence amount of crosstalk arising between the specific signal wire and the two adjacent signal wires. An adjustment quantity calculation portion calculates an adjustment quantity representing a degree of decrease of a slew rate of the specific signal, based on the adjustment coefficient, the specific signal and the two adjacent signals. A driver adjusts the slew rate of the specific signal based on the adjustment quantity and to transmit one of the output signals corresponding to the specific signal.
