2.4.5.1 ECOs to Enable the DP83TC812R (AWR2944EVM) or DP83TG720S (AWR2944PEVM) PHY

By default, the board is designed to be used with the DP83867E PHY with the RJ45 connector. To enable the DP83TC812R PHY with the MATEnet connector, the following hardware changes must be made. For help with locating these components on the PCB, refer to the provided Schematic, BOM, and assembly files.

  1. Remove R98 and populate on R74
  2. Remove R101 and populate on R230
  3. Remove R103 and populate on R96
  4. Remove R105 and populate on R100
  5. Remove R121 and populate on R178
  6. Remove R122 and populate on R225
  7. Remove R195 and populate on R245
  8. Remove R290 and populate on R234
  9. Remove R325 and populate on R237
  10. Remove R336 and populate on R238
  11. Remove R338 and populate on R239
  12. Remove R339 and populate on R240
  13. Remove R413 and populate on R247
  14. Remove R369 and populate on R249
  15. Populate D18 and D19 ESD diodes
  16. Populate C55
  17. The bootstrap configuration pins can be populated/removed as needed depending on the use case
    Note:

    The automotive Ethernet PHY (U4) and port (J4) on the AWR2944EVM have not been tested by Texas Instruments to be compliant with any regional standards such as Radio Equipment Directive 2014/53/EU. If the user wishes to populate the components necessary to utilize this port, then users can do any necessary testing to verify that the port is compliant with all applicable regional standards before use. Any modifications done to enable the J4 port invalidates the existing RED 2014/53/EU certification of the AWR2944EVM.
