Transmission circuit and semiconductor device

摘要

There is provided a transmission circuit which can certainly perform transmission of data of digital form between two circuits operating in synchronization with two clock signals having the same frequency even if phase shift is generated between the two clock signals. According to a phase difference between a clock signal CK1 and a clock signal CK2, the transmission circuit performs either one of an operation of outputting pre-transmission digital data inputted to the transmission circuit as it is or after it is inverted, and an operation of sampling it in synchronization with the clock signal CK2 and outputting it as it is or after it is inverted.
