Systems and methods for storing frequency information for system calibration/trimming

Abstract:

Embodiments of the present disclosure include a microcontroller with a frequency test circuit, a device-under-test (DUT) input, and a calculation engine circuit. The calculation engine circuit is configured to compare a measured frequency from the frequency test circuit measured from the DUT input to a reference frequency stored in memory, and, based on the comparison, adjust frequency of the DUT generating the DUT input.
