Parallel interface and integrated circuit

摘要

A parallel interface is disclosed. The parallel interface of the present disclosure includes an input unit configured to input, in parallel, a plurality of predetermined data signals and a clock signal; an output unit configured to output, in parallel, the predetermined data signals in synchronization with the clock signal; and a plurality of transmission lines disposed between the input unit and the output unit and configured to transmit, in parallel, the predetermined data signals and the clock signal, wherein the transmission lines are configured with a wiring pattern in which the transmission lines have different electrical lengths and an equal electrical capacitance.
