We are making our board with POE based at TPS23756 EVM.
Only main difference is using ETH1-230LD instead of integrated transformer due to mechanic reasons.
We have seen that ETH1-230LD is a lot of used in your designs, but we have some doubts.
For example in designs SLVU687 and SLUA454 this transformer is connected in various way
(changed RX and TX parts and also changed + and - polarity, respecting official
data sheet).
It is surelly OK, but can you confirm us that it is OK for this transformer (TX and RX
can be interchanged and also polarity) ?
Would you be so kind to check connection also in attached SCH concerning POE, because
all your designs have POE port + RJ45 as data port, while I will have standard PHY (chip) located at
board. Discard secondary port. It is standard ethernet port.
Thank in advance , regards
