  • RE: DP83869HM: SGMII signal integrity

    Hillman Lin said: For the next steps for debug, are you able to do a MII loopback on PHY2 and check the package on the MAC side to see any package drop? The detail information will be on 9.3.4 in the datasheet or register 0x0000 I now checked what information…

  • DP83869HM: SGMII to RGMII bridge mode settings

    TI Thinks Resolved
    Part Number: DP83869HM Hello, My customer wants to use the DP83869HM in SGMII to RGMII bridge mode. To configure SGMII to RGMII brighe mode, the customer connected 4 pins according to following table 9 guide. However, SGMII to RGMII bridge mode setting…

  • RE: DP83869HM: EMI / EMC Guidelines for Clock and Other Signals

    Hi Melissa, Thanks for your information on queries. I have one more query on SMI Interface (Serial Management Interface). As per IEEE 802.3-2022 Clause 22 Section 22.3.4, Delay between MDC and MDIO can be 0ns (Min) to 300ns (Max). But in DP83869HM…

    Gerome Cacho said: so long as there is no swapping who talks with who Gerome commented: " 2x DP83869's may help with this application so long as there is no swapping who talks with who." What does Gerome mean when stating: so long as there…

  • RE: DP83869HM: Phy not responding after re-programming FPGA

    Hi Jacob, Is there a way to figure out what state the FPGA pins are in after they are programmed ? Another thing I can think of is that the RX_D0 and RX_D1 pins connected to FPGA might have changed the PHY address state when FPGA is getting programmed…
