Responding to: ???'s previous message
Dear Kai,

yes i got it now correct. If I connect b5 to DVcc pin of micro direcly that is wehre C28 is connected tha i wouldnt need that R27. Doing that will require routing changes and that new routing will be little more difficult and tricky than present routing. If we consider performance what is better present layout or the one obtained with connecting B5 bead directly to DVcc pin of micro? The Atmel datasheets show bead connected to DVcc pins.

I am more worried about measurement accuracy than anything else.

Thanks & Regards,
Prahlad Purohit
