A receiver has an oscillator to output an oscillation signal, a receiver to perform reception processing of a reception signal, a phase frequency detector to output a first signal in response to a phase and a frequency of the oscillation signal so as to generate a second signal indicating a reference phase, a differentiator to generate a third signal being a difference between the first signal and the second signal, an oscillator controller to generate a fourth signal for controlling a phase and a frequency of the oscillator, a phase initializer to output an initialization signal for synchronizing a phase of the second signal with a phase of the first signal, a trigger signal generator to output a trigger signal indicating timing with which the phase initializer outputs the initialization signal, and a power supply controller to control whether to supply a power supply voltage.
