Patent ID: 8536953

Claim:
A quartz oscillator module comprising: a first quartz oscillator comprising two terminals connected to an electronic device, wherein the first quartz oscillator provides a first clock signal to the electronic device; a second quartz oscillator comprising two terminals connected to the electronic device, wherein the second quartz oscillator provides a second clock signal to the electronic device; a first electronic switch comprising a control terminal receiving a first control signal, a first terminal connected to a power supply, and a second terminal connected to the two terminals of the first quartz oscillator respectively through a first capacitor and a second capacitor, wherein the second terminal of the first electronic switch is further grounded, the first control signal makes the first terminal connect or disconnect with the second terminal, when the first terminal is connected to the second terminal, the first quartz oscillator is not activated, when the first terminal is disconnected from the second terminal, the first quartz oscillator is activated; and a second electronic switch comprising a control terminal receiving a second control signal, a first terminal connected to the power supply, and a second terminal connected to the two terminals of the second quartz oscillator respectively through a third capacitor and a fourth capacitor, wherein the second terminal of the second electronic switch is further grounded, the second control signal makes the first terminal connect or disconnect with the second terminal, when the first terminal is connected to the second terminal, the second quartz oscillator is not activated, when the first terminal is disconnected from the second terminal, the second quartz oscillator is activated.
