Abstract
A micro electro mechanical system (MEMS) oscillator supplies an oscillator output signal having a first frequency that differs from a predetermined frequency of the output signal. An error determination circuit determines frequency error from the predetermined frequency based on initial frequency offset and/or temperature and provides the error information indicating a difference between the first frequency and the predetermined frequency. The error information is used by a receiving system in frequency translation logic that utilizes the oscillator output signal as a frequency reference.
