Abstract
According to a clock generator, an oscillator outputs source oscillation clocks which are trimmed according to a trimming code. A first frequency divider generates X frequency division clocks by frequency-dividing the source oscillation clocks by a first frequency division ratio X. A trimming controller changes the trimming code within a period of the X frequency division clocks and supplies the changed trimming code to the oscillator.
