  • DP83620: Need MDC Frequency wrt RMII

    Part Number: DP83620 Hi Experts, We are using DP83620 Ethernet PHY Transceiver in our design. In datasheet, section 4.7 AC Specifications — MII Serial Management Timing table MDC Clock Frequency provided. We need MDC Clock Frequency of the same wrt to…

  • DP83620: MDC to MDIO Time Delay Issue

    Part Number: DP83620 Hi Experts, In our Project, we are using DP83620SQE/NOPB Ethernet Transceiver (RMII mode). During DVT Testing of Ethernet section, We have identified failure in MDC to MDIO (output) Delay Time with respect to Datasheet. …

  • RE: DP83620: signal values of PMD output pair signals slightly exceeding 1.05V

    Hi Premalatha, The signals should be measured with a high impedance differential probe. The setup you used initially is correct. I was just trying to eliminate any errors contributed by probe and scope. This is the setup required DP83620 -> 50ohm resistor…

  • DP83620: MDC rise and fall time

    Resolved
    Part Number: DP83620 Hello Team, are there any restrictions on the MDC's rise or fall times. Is 40 ns (10%-90%) at 2.5 MHz still OK? We have no MDIO communication problems with the PHY. Best regards Dieter Dornberger
