DP83848I: EFT burst test causes network connectivity to drop

Part Number: DP83848I

The customer is using the network chip DP83848IVVX and is experiencing problems. When the EFT burst test is applied, the network port indicator will be off and the network connection will be disconnected. This should be a hardware issue.
After the EFT pulse test, it can only be recovered for a while, and then it will be disconnected, and several prototypes tested have this problem. The following figure shows the schematic of the DP83848:

  • Hello,

    Can you please respond with the following information so I can establish more of a baseline?

    - What is the link partner?

    - What level is it failing at, and what level are you trying to achieve?

    - When the PHY does lose link, what is the time that is needed for it to recover link?

    Sincerely,

    Gerome
