Beschreibung
Zusammenfassung:	An oscillator includes: an external terminal, a resonator, and an oscillation circuit that oscillates the resonator, in which the oscillation circuit includes an amplification circuit and a current source which supplies a current to the amplification circuit, in which the current is set according to a first control signal which is input from the external terminal and a drive level of the resonator is changed according to the setting of the current.
