Abstract
A circuit device is configured to switching between a first mode in which phase noise of an output clock signal is lower than that in a second mode and the second mode in which power consumption is smaller than that in the first mode, and the circuit device includes an oscillation circuit configured to generate an oscillation signal, a waveform shaping circuit configured to perform waveform shaping on the oscillation signal to obtain a rectangular wave clock signal; and an output circuit configured to output the output clock signal based on the clock signal. A driving capability of the waveform shaping circuit in the first mode is higher than a driving capability of the waveform shaping circuit in the second mode.
