    摘要: A method for adjusting an oscillator clock frequency, comprising: providing a first oscillator, applying a first setpoint value to the first oscillator, determining a first oscillator frequency value within a first time frame, providing a second oscillator, applying a second setpoint value to the second oscillator, determining a second oscillator frequency value within a second time frame, determining a new frequency setpoint value from the first and second frequency values, the first and second setpoint values, and a desired frequency value, and applying the new frequency setpoint value to one of the first and second oscillators.
