PROBLEM TO BE SOLVED: To provide, by adding a small-scale circuit to a conventional configuration, a timing generating circuit enabling large calibration without affecting timing-setting range of a user. SOLUTION: A timing generating circuit, which generates, according to a reference clock and read data from a timing data storage to which rate signals and control signals for selecting timing data are input, timings for each rate, and which stores output data of an adder for adding calibration values of rising and falling edge to timing data set by a user, includes a skew adjustment unit, which in turn includes a delaying circuit for sending control signals and the rate signals.
