摘要： A PLL device includes a voltage control oscillation unit, an analog/digital converter, a quadrature demodulation unit, a comparison signal output unit, a phase difference detection unit, a loop filter, and a digital/analog converter. The quadrature demodulation unit quadrature-demodulates the digital feedback signal to obtain an in-phase component (I component) and a quadrature-phase component (Q component). The comparison signal has a set frequency of the output signal when the feedback signal is the output signal and has a frequency obtained by dividing the set frequency by the dividing number when the feedback signal is the frequency division signal. The phase difference detection unit obtains a phase difference between the digital feedback signal and the digital comparison signal based on the I component and the Q component of the digital feedback signal and the I component and an Q component of a comparison signal.

摘要： An oscillator includes a nominal frequency output unit, a frequency adjustment amount output unit, a gain output unit, a multiplier, and an adder. The nominal frequency output unit is configured to output a first digital value corresponding to the nominal frequency. The frequency adjustment amount output unit is configured to output a second digital value corresponding to a rate of frequency in order to set a frequency adjustment amount with respect to the nominal frequency using the rate of frequency. The gain output unit is configured to output a third digital value corresponding to a gain to be multiplied by the second digital value. The multiplier is configured to multiply the second digital value by the third digital value, thus outputting a fourth digital value. The adder adds the first digital value and the fourth digital value to output the added result as a setting signal of frequency.
