Tool/software:

Hello,
When we read the revisions of the product with the part number DP83869HMRGZT, which we purchase as a company and use in our products, via the register, we get different revision information.
We cannot see the differences between these revisions on the datasheet. We only see the note that the revision changes when there is a major change. Can we learn the differences between the revisions and if there are separate datasheets for the revisions?

Thanks.

Hi,

Could you check register 0x0003 and see what revision are you currently working on?

The main changes between the older revision and new revision on DP83869 are the link status on Fiber application.

The following appnote are the fix for the new revision of DP83869

Hi,

We saw 2 different revisions in the PHYs we use.

For Revision 1 = The value read from the PHYIDR2 register (address = 0x3) is (0xa0f1).

For Revision 3 = The value read from the PHYIDR2 register (address = 0x3) is (0xa0f3).

No PHY with revision 2 was found.

Thanks.

Hi Demirel,

We don't have the revision 2 for DP83869 publicly. Only PHY revision 1 and 3.
