Part Number: TLK110
Other Parts Discussed in Thread: DP83822I

Hi team.

I'd like to change TLK110 to DP83822I.

Could you tell me about the register settings.

Accoridng to the data sheet, I think that  it is the difference only in PHY Identifier Register #2.

Is it correct?

If no, could you tell me where to change the register?

Sincerely.

Kengo.

    Hi Kengo,

    DP83822I has same functionality as TLK110 but it is not drop in replacement. You are correct in saying that 0x0003 PHY Identifier Register #2 is different between DP83822 and TLK110. There is a lot of overlap in registers for TLK110 and DP83822. However, there can be some other register differences between the two devices.It depends on which features are you currently using in TLK110. You can then check the corresponding registers in DP83822 datasheet. If its same then you do not have to make any changes. If you see some differences that you are not sure about, you can post specific questions as new thread.

    -Regards
