Could someone give me the relative X and Y distances between the PCIe and FMC connectors? I am designing a board which plugs into both (using another board in between) and need to know those relative locations. It is not directly specified in the online documentation that I can find.

Thanks,
John

Our designer took a couple extra measurements which our captured in the following image (measurements in mils):

Looking at the lower peg of the PCIe connector (306, 1565.5) and the left peg of the FMC connector (769.5, 361), the relative XY distance from each other is
Relative X direction = 769.5 - 306 = 463.5mils
Relative Y direction = 1565.5 – 361 = 1204.5mils
