Part Number: DS250DF410
Other Parts Discussed in Thread: SIGCONARCHITECT

Hi there:

I'd like to check the code of configuration for our customer for 10Gbps application.

Besides the Reg_0x2F need to set as [00] or [10], what suggestion need to modify about their register set-up?

    Hi Kay,

    All we need to do is to set reg 0x2F[7:4]=4'b0000.
    Also, it is a good idea to reset the device after this setting. You can do this by setting:
    0x0A[3:2] = 2'b11
    0x0A[3:2] = 2'00

    It would be a good idea if your customer can put a connector on their board for SMBus interface: SDA, SCL, & GND. This will enable us to use SigconArchitect GUI to directly control the device.

    Here is my email address: Nasser.mohammadi@ti.com. Please let us know about the application for this project.

    Regards,,nasser
