Hi Miles,
The following register writes can be used on a single board to generate ethernet packets directly on the RGMII interface. Can you please write these two registers on the DP83TC812 and then probe the RX_D0 signal? You may try this experiment…
Hi Aniruddha,
Do you think there could be something wrong on a hardware level with one or both of the EVM boards we've received?
Should we be looking at getting an exchange or do you think there might be something else on a firmware/process level…

Hi,
I'm trying to make Automotive PHY (DP83TC812R-Q1) work on AWR2944 Rev. D EVM.
What I did are: 1. Do the EVM Eco modification according to www.ti.com…
Hi Yuwei,
Just to clarify, is your issue still with the AM62A7 recognizing the PHY through MDIO/MDC?
YuWei Wu said: Originally, the connection was from TI DP83TC812S to TI DP83TC812EVM-MC.
We've changed the connection and now use TI DP83TC812S and NXP TJA1100…
Part Number: DP83TD510E-EVM Tool/software: In SPE(Single pair Ethernet) testings on CAT6 cable of 8ohms resistance per 100m ,its working up to 600m and on power cable of 1.5sq mm 10 conductor cable its working only 300m and resistance value is 2 ohms…
Hi JD,
When you say the schematic is the same as our development board, do you mean our DP83TC812MC-EVM? Is the layout the same aswell?
The DP83TC812 meets IEC61000-4-2 ESD classification level 4 for pins 12 and 13: ±8-kV contact discharge at a performance…
Hello Mo,
Yes, it is possible. Below is an app note detailing one use case of daisy chaining Single Twisted-Pair Ethernet (SPE) specifically the DP83TG720 and the DP83TC812.

Part Number: DP83TC812R-Q1 Other Parts Discussed in Thread: DP83TD510E Hi all,
Is it possible to use EtherCAT with your SPE PHYs?
We are using the Sitara AM64 with the industrial communication EtherCAT stack from TI and would like to use them with either…
Hello Krishna,
If you want to use our DP83TC812 PHY then the only way to have RJ45 as an output would be putting two DP83TC812 EVM's back to back so it would look like this:
PC -> EVM #1 RJ45 -> EVM #1 Matenet connector -> EVM #2 Matenet connector…
