Synchronizing Analog Input and Output

Last Modified: January 31, 2020

You can time analog output events and synchronize the events to the analog input clock. You can share a common clock for A/D and D/A conversions to ensure that both occur simultaneously. The advantage of this method is that, so long as your software completes in time, you mask out jitter. One caveat is that outputs are always one loop cycle behind the inputs, as shown in the following figure.
