Compute Module • Compute module 5 IO board. PCIE lanes inverted

Hi all,

I have noticed that the lanes on the PCIe seem to be inverted.

PCIE_TX and PCIE_RX have the p and n lines inverted --> (Pins 49 for 47 and 43 for 41)
I have checked the specification against several designs and i am very confused about this. I guess this PCA has been tested and i must work but i am not sure why this lanes are inverted p to n.

I am designing a new PCA customized and i would need to know wheter it is a error or it is totally fine and why.

Have you tried this connectivity?

Regards!
