1. A device for generating an output signal having a frequency, the device having a die temperature, comprising:

  • a first temperature sensor to sense a first temperature;

    a non-volatile memory to store calibration information for controlling the output signal frequency as a function of the first temperature;

    a semiconductor oscillator to generate the output signal as a function of the calibration information; and

    a select input to select the output signal frequency as a function of an external passive component.
