Do I need to use series termination for PPI data bus lines? I know that they are required for DDR chi interface. I also understand that series termination is reauired for PPI sync and clock lines lines.I am not clear about the PPI data lines. Due to space problems on the board, I do not want to place them, if not essential.
Another question is do I need to match the trace lengths of PPI data bus? If so, to what accuracies? and what is the max length allowed for the PPI data bus lines?
