Abstract
A system for determining a data converter operating mode includes measurement circuitry which measures a master clock frequency, measures a frequency ratio between a frequency of a data clock signal and the master clock frequency, and measures a selected operating condition of the data converter. A mapping system maps the measurements of the master clock frequency, the frequency ratio, and the selected operating condition, to an operating mode of the data converter. In another embodiment, the measurement circuitry adjusts the measurement of the master clock frequency in response to a measurement of the operating conditions of the data converter. In a further embodiment, user input information varies the measurement of the master clock frequency.
