PLL DEVICE

摘要

A PLL device includes a variable frequency oscillator and a frequency divider section. The variable frequency oscillator varies an oscillation frequency in response to a control signal including information on a phase difference between a reference signal and a frequency division signal and oscillates an output signal obtained by multiplying a frequency of the reference signal. The frequency divider section frequency-divides the output signal to generate the frequency division signal. An injection locked frequency divider is arranged in the frequency divider section, the control signal is input to the injection locked frequency divider, and the operation frequency of the injection locked frequency divider is controlled by the control signal.
