Abstract
To provide a clock signal generating device that changes the frequency of a predetermined clock signal in a short time and prevents or mitigates instability in the operation of the supply destinations of the clock signal when the frequency of the clock signal is changing.The clock signal generating device is provided with a second control unit that, when the target frequency changes, successively changes the voltage impressed on the clock signal generating unit with a preset change value and a preset interval in a preset time in place of the first control unit, causing the frequency of the clock signal newly generated by the clock signal generating unit to approach the target frequency.
