looking for some advice on how to handle this situation. Ideally, pairs ABCD need to be swapped to DCBA (rollover basically, not the xover that Auto-MDI is supposed to solve). Is it possible to roll the pairs or how do you unroll this scenario? (U18/19 are ESD TVS, PHY is on right, left is magjack with pin 1 A- at bottom)
Board is 4 layers with 2 central ground planes, but I’d like to avoid vias for this if possible. Yes, run is short, and can be closed up even more. I have some room to move things around in this part of the board.
Bonus question: How do you guys design footprints for TVS ESD blocks (where one side is usually NC and the pair routed through). Leave it NC? I tried making opposite pins same “number” and that made KiCAD go a little whacky with dp routing.
Thankful for any advice or pointers.
