DP83822HF: DP83822HF

Part Number: DP83822HF

Good morning!

In our schematic we substituted the PHY KSZ8081MNXIA with PHY DP83822HFRHBT.

Attached there is the complete scheme.

We have the following problems:

  • TXD0/TXD1/TXD2/TXD3 pins do not move, they are always LOW.
  • Twincat does not find the EtherCAT node.

Can you help us the understand the mismatch in the schematic?

There are particular settings in the ET1100 to communicate with the phy DP83822?

Thanks in advance

Tiziana
