Bus_PCI_Express_Mini

Hello,
I’m just trying to add a m-Pcie symbol in a schematic and something is not clear.

PETp0 and PETn0 are configured as input.
PERp0 and PERn0 are configured as output.

I have checked in mPCIe documentation. If I undertand, PET is transmission line from point of vue of mPCIe module. Why is PET tagged as input and not output ?

Regards,

JB

I know nothing about this, but I like to think I can Google reasonably well . . .

Thanks a lot for your answer. I have found some contradictory answers with google (and a lot of answers that don’t help).

Yes…lot of garbage out there. If you want to increase ambiguity and confusion try to use some IA engines.

I don’t use IA. I have found some ambiguity in regular paper documentations.
