To provide an oscillator, etc., that can reduce micro-jumps in frequency caused by fluctuations in temperature measurement results and achieve higher precision in clock frequency.SOLUTION: An oscillator 4 includes a vibrator 10, a first circuit device 20 electrically connected to the vibrator 10, and a second circuit device 30. The first circuit device 20 performs a first temperature compensation process of generating a first clock signal CK1 by causing the vibrator 10 to oscillate, and temperature-compensating the frequency of the first clock signal CK1. The second circuit device 30 performs a second temperature compensation process of inputting the first clock signal CK1 from the first circuit device 20, and generating a second clock signal CK2 on the basis of the first clock signal CK1 and temperature-compensating the frequency of the second clock signal CK2.SELECTED DRAWING: Figure 1 【課題】温度計測結果の揺らぎなどを原因とする周波数のマイクロジャンプを小さくして、クロック周波数の高精度化等を実現できる発振器等の提供。【解決手段】発振器４は、振動子１０と振動子１０に電気的に接続される第１回路装置２０と、第２回路装置３０を含む。第１回路装置２０は、振動子１０を発振させることで、第１クロック信号ＣＫ１を生成すると共に第１クロック信号ＣＫ１の周波数を温度補償する第１温度補償処理を行う。第２回路装置３０は、第１回路装置２０からの第１クロック信号ＣＫ１が入力され、第１クロック信号ＣＫ１に基づいて第２クロック信号ＣＫ２を生成すると共に第２クロック信号ＣＫ２の周波数を温度補償する第２温度補償処理を行う。【選択図】図１
