Abstract
An ILFD controller sets a control parameter on the basis of a frequency of a frequency-divided signal and a frequency of a reference signal measured by a clock counter. A VCO controller selects an oscillation band that defines an oscillation frequency of a VCO and also selects an oscillation band of the VCO on the basis of the frequency of the reference signal and a frequency of a frequency-divided signal that is a result obtained by frequency-dividing an output signal, which is delivered from the VCO in response to the selected oscillation band, by means of an ILFD and a frequency divider.
