Abstract
An oscillator includes a circuit device, a clock output terminal, an error output terminal via which an error signal is outputted, and a clock input terminal, and the circuit device includes a clock signal generation circuit that generates a clock signal, an error signal generation circuit that generates the error signal, and a selection circuit that selects one of the clock signal and a signal inputted via the clock input terminal based on the error signal and outputs the selected signal via the clock output terminal.
