Abstract
A crystal offset value is stored in non-volatile memory in an oscillator device. The crystal offset value corresponds to a ratio between a rated frequency of an output of a crystal oscillator and a measured frequency of the output of the crystal oscillator. A rated divide value that corresponds to a selected frequency for an output of the oscillator device assumes the crystal oscillator operates at its rated or ideal frequency. Thus, the rated divide value corresponds to the rated frequency. The rated divide value is adjusted by the crystal offset value to generate an adjusted divide value and the adjusted divide value is used to generate an output signal of the oscillator device with the selected frequency.
