Abstract
A system for determining a data converter operating mode includes measurement circuitry that measures a master clock frequency of a master clock signal received without a modification in frequency from a master clock signal source and that measures a frequency ratio between a frequency of a data clock signal and the master clock frequency. A mapping system maps the measurements of the master clock frequency and the frequency ratio to an operating mode of the data converter. In other embodiments, mapping systems map the measurements of the master clock frequency and the frequency ratio to an operating mode of the data converter based on mode priority constraints. In additional embodiments, mapping systems map the measurements of the master clock frequency and the frequency ratio to an operating mode of the data converter by narrowing the choices of master clock divide ratios and subsequently determining an operating mode from the frequency ratio.
