Noise filter on power line for ADuM1100

Dear Sir.Madam,

I have a question for your ADuM1100 i-coupler,

Our customer is proceeding to pwb design to use ADuM1100.

So as for the power supply,

Should we put the LC filter on the power-line for switching noise reduction like return back to power-line?

Otherwise we dont care of putting LC filter, correct?

Connect VDD1 to power-line directly,OK?

Thanks Kaos
