Rush,
Just to confirm, are you using the DP83848I-MAU-EK board ( www.ti.com/.../dp83848i-mau-ek) Or is this a board of your design with the DP83848I and the PIC microprocessor co-located on the same board?
Also, could you clarify what you mean when…
Hi Vilem,
My feedback is that you should consider decoupling for your supply rails. I'd suggest using the DP83848I-MAU EVM as a reference design and only removing items from that schematic you are sure you do not need.
You also have connections…
Hi Lam,
Please take a look at our DP83848 design and layout guide. Section 5 specifically addresses MII/RMII design:

For an example schematic/layout, you can use the DP83848I EVM below as an example:

Chirag,
We have some recommendations on the RJ-45 and MDI connections in our Ethernet Design and Layout guide (http://www.ti.com/lit/pdf/snla079).
You can also see an implementation of this in the DP83848 MAU schematics (http://www.ti.com/lit/pdf…
The DP83848 devices in a 48 QFP share a common evaluation board, the DP83848I-MAU-EK. This board is available at:
http://www.ti.com/tool/dp83848i-mau-ek
The board files (user guide, schematic, layout, bill of materials) are available on both the product…
Hi Anirudhha,
I sent the layout and schematic to your outlook address.
Recommend customer to take the layout of TI board as reference which shows good layout practices:

The DP83848I has the same package as the DP83848C. Therefore, you can use the DP83848I EVM as a reference. It is available on-line at:
www.ti.com/.../dp83848i-mau-ek
The requirements for crystal parameters are in the datasheet and in the design and…
The external components are very similar. The easiest way to see this is to compare the base (non-PoE) EVMs for the the DP83848I ( www.ti.com/.../dp83848i-mau-ek) and the DP83849IF ( www.ti.com/.../dp83849ifvs-evk)).

There are a few notable aspects here:
The IEEE specification does specify 68 Ohms impedance for the MII signals, and specifically notes this requirement for "electrically long transmission paths or path segments". Note that the IEEE specification is…
