Hi Devitt,
Can you please get hold of EVM on ti.com and do the same compliance? This will give us an indication if there is any setup issue which is causing the failure. The EVM design is tested for compliance and we can use this as golden device.

Hi,
The Ethernet PHY is integrated within the TM4C129ENCPDTI3R MCU. You don't need an external PHY. But please follow the system design guideline on the selection of transformer and protection diode. Below will aid your development.

Part Number: DP83848I Hi,
I have a board with DP83848I that we have made that appears to be getting hotter than expected. The board is powered off POE power with a LM5166YDRCR 3.3v regulator. this powers the MCU without any issues and appears to be very…
The DP83849IF device is a dual port device that supports copper and fiber. The DP83849IF EVM ( www.ti.com/.../dp83849ifvs-evk) includes a connector that would support connection to a PoE daughter card, but does not include any PoE circuitry on the EVM…
Part Number: DP83848YB Other Parts Discussed in Thread: DP83848I-MAU-EK I am having a problem daisy chaining two DP83848YB parts in a JTAG chain. I had problems on my board with my 6 device JTAG chain. I jumpered around the DP83848YB parts and everything…
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…
Hello Sooraj,
We do not have a DP83620 PoE reference design but we do have a DP83848I PoE reference design. See the PoE-PD reference design here: www.ti.com/.../snoa476c.pdf
To begin a PoE solution with the DP83620, you could start by replacing the…
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…
