  • DP83849IF: Auto-negotiation Time Out

    Part Number: DP83849IF Hi, I think there is an algorithm that sets a timeout on the MAC side during auto-negotiation, and if it doesn't go well, restarts and repeats this, but there doesn't seem to be any regulation for this time itself. What timeout…

  • DP83849IF: Unidirectional gateway

    Resolved
    Part Number: DP83849IF Hi, I have to develop an unidirectional Ethernet gateway (10/100 Mbps) with a physical isolation. For this, I would like to use the 2x IC DP83849IF (copper to fiber) in media convertor mode (A -> B) <- fiber -> (B -> A) and connect…

  • RE: DP83849IF: DP83849IF

    Hi Andrey, Sorry for the confusion. I was mistaken when I said that BIST would not cover the PHY in media converter mode. If you test Port A and Port B separately, this will cover each port. It works by generating packets through the PRBS and looping…
