I m using LS1028A Layerscape Processor for my project. I need some clarifications regarding power section of the processor.

1)I m not using USB,DisplayPort feature ..Do i need to put power supply to those power supply pins??

2)Do i need to put Filtering circuit to PIXEL_DVDD and AVDD_PIXEL pins even if i m not using DP??

 

Kindly suggest what to do with the above unused pins

1) Refer to the AN12028 - QorIQ LS1028A Design Checklist, Table 3. Power and ground pin termination checklist (and notes after the table).

DP supplies have to be applied for the LS1028A even if DP is not used.

2) The filtering circuits are not needed in this case.
