Ensure PDN analysis has been performed, and the required number of decoupling and bulk capacitors are provided for all the power supply rails including the Dual-voltage IO supply rails.
Place the decoupling capacitors as close as possible to the supply pins. Larger bulk capacitors can be placed further away.
Use low ESL capacitors and mount them with shortest possible traces to keep the mounting inductance low. For more information, refer the Sitara Processor Power Distribution Networks: Implementation and Analysis application note.
The bulk and decoupling capacitors values from the SK can be used as a reference when PDN analysis is not performed or results are not available. For filtered (ferrite) power supplies implementation, follow the device-specific SK.
