Abstract: A frequency modulator apparatus of phase selection type that relaxes the restrictions as to the phase range of modulation clock signals. This frequency modulator apparatus of phase selection type comprises a poliphase clock signal generator circuit (101) for generating N-phase clock signals; a control circuit (104) for sequentially activating first clock selection signals that instruct which ones of the N-phase clock signals should be selected; an edge appearance time adjusting circuit (103) for adjusting the rising edge and/or falling edge appearance times of the first clock selection signals outputted from the control circuit (104) to output second clock selection signals; and a modulation clock signal generator circuit (102) for selecting, in accordance with the activation state of the second clock selection signals outputted from the edge appearance time adjusting circuit (103), one of the N-phase clock signals to output a modulation clock signal (MCK).
