TPS23861: 4 port PoE PCIe card

Hi Gareth, unfortunately we do not have a block diagram for PCIe with PoE.

For the applications that I have seen for PSEin PCIe schematics, the PSE design is the same as the TPS23861 EVM below. You may consider the schematic in the user's guide to use as reference for the PSE piece of the PCIe application. Please let us know if this helps. Thanks!
