摘要： Methods, systems, and circuitries are provided to generate clock signals of different qualities in a device. A method includes determining whether the device is operating in a mid power mode or a high power mode. In response to determining that the device is operating in the mid power mode, oscillator circuitry is controlled to cause the oscillator circuitry to consume a lower amount of power, such that the oscillator circuitry generates a lower quality clock signal. In response to determining that the device is operating in the high power mode, the oscillator circuitry is controlled to cause the oscillator circuitry to consume a higher amount of power, such that the oscillator circuitry generates a higher quality clock signal. The lower amount of power and the higher amount of power are different from one another.
