Hello, I would like to ask if it is possible to confirm whether a chip is an authentic AD9361/AD9363/AD80321 by using the Product ID Register (Address 0x037). I am asking because I am not sure if the chip I purchased has had its markings altered by grinding. If this method cannot determine the authenticity, are there any other ways to confirm it?
