Abstract
An analog-to-digital-converter (ADC) timing engine may simplify the use of Delta-Sigma ADCs by compensating for the group-delay of the ADC. The compensation may render the group-delay corresponding to the ADC largely transparent to the end-user of the ADC. Therefore, multiple ADCs may be easily synchronized with each other, even if they have different group-delays, and they may further be synchronized with other types of ADCs that do not have group-delays. The data from the ADCs may also be synchronized with external events. The ADC timing engine (ATE) may be programmed with a number of parameters to set proper delays taking into account not only the group-delays corresponding to the various ADC, but delays stemming from a variety of other sources. Multiple ATEs may be synchronized with each other to ensure that data acquisition by the participating ADCs is started and/or stopped at the same point in time.
