May I ask, BCM56870A0KFSBG has three positioning holes. How can we determine if it is an original product?
We are an authorized distributor for Broadcom Limited.
If you purchased it at DigiKey we can verify the part markings are correct for what was ordered.
You can email techs@digikey.com with the picture of the top part markings and the DigiKey Invoice/Sales Order it was purchased on and we can get the manufacturer to authenticate.
