ABSTRACT:
A clock producing apparatus for a D/A converter switches the clocks in accordance with the inputted sampling frequencies. A deterioration in the S/N caused by unnecessary spectra which are caused by the inputting of different sampling frequencies is prevented.
The selecting operation is effected by the selecting circuit so as to obtain the selected input sampling frequencies, and at the same time, the clock signals are prevented from being inputted to the frequency dividing circuits corresponding to the input sampling frequencies which are not selected. Therefore, unnecessary spectra are prevented from being generated.
