Abstract

An integrated circuit comprises a first circuit that receives a clock signal. A first temperature sensor senses a first temperature. Non-volatile memory that communicates with the first temperature sensor outputs calibration data as a function of the first temperature. A semiconductor oscillator that communicates with the non-volatile memory and the first circuit generates the clock signal having a frequency that is related to the calibration data. A select input selects the frequency of the output signal as a function of an external passive component.
