DP83849I: Question of applications for DP83849 Series

Part Number: DP83849I

Hello?

As the title, I want to ask applications.

1. Is it can design for 'Bus network' using one of micro-controller(it has one of MAC) and one of this chip?

  - micro-controller(uC) <->DP83849 ; MII or RMII

  - DP83849<->P1 or P2(included magnetics) ; ethernet

2. Do you plan to develop QFN package(included thermal pad) of this product, likes DP83848?

Thank you.

  • Hello,

    I am having trouble following your question. Are you asking if this application can be possible? If you review our System Block Diagram in section 1.4 you can see that we have a similar diagram to your question.

    We do not have a QFN package for this.

    Thanks,

    Cecilia

  • I reviewed the block diagram, but that is using for two of MAC, so I asked.

    The point is "It can operate two port using 'one' of MAC or not." and "It can using for ethernet switch or not.".

    Unfortunately QFN package doesn't exist, but that's fine.

    Thank you for your reply and please one more time.

  • We have an app not that discusses the option to port switch where either of the MAC interfaces may be assigned to ports A or B. I don't believe you can share the MAC, however, you may switch between each port.

    Thanks,

    Cecilia
