How to Verify the Authenticity of the Chip

Category: Datasheet/Specs
Product Number: AD9361

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?

  • HI  

    Product ID is used to check for Communication interface. The best way of to check authenticity, you have top marking on the chip which includes the lot code and Date code. Pls take a close picture of IC, so we can read these details and approach to local sales or register support case. So, our backend team will trace the authenticity of the chip.

    Regards,
