ABSTRACT:
A system for determining a data converter operating mode including measurement circuitry operable to measure a master clock frequency by comparing a frequency of a master clock signal and a frequency of a fixed frequency clock signal and operable to measure 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 one particular embodiment, the fixed frequency clock signal is provided by an oscillator. In a further embodiment, the master clock signal is generated by multiplying the frequency of another clock signal.
