Yes, it is interesting to see what the required decoupling is (and

will always be some unknowns that there is *no time to solve* of you
are ever going to ship your product.


Can you give an example of some of these unknowns?


It is not always known of what are the effective sources of the EMI on the part and what is the path of the EMI currents.
Take the datasheet on the СS42438 and guess how to connect it.

Also, is not always known what kind of wicked resonances does have the board, since it depends on many factors.

The point I am trying to make is of course it is necessary to understand what is going on, however you will always have to do some EMC work, no matter how good is the theory.
