Hi,
I'm confused about zed boards routing of diffpair to the FMC connector. According to ZedBoard_HW_UG_v2_2.pdf, page 21:
Note, the following LPC FMC connections guidelines were followed:
CLK_#_M2C
– 50 ohm single-ended impedance
...
LAbus
– 50 ohm single-ended impedance
...
Diff pairs are suposed to be routed with 100Ω differential impedance, and P/N traces typically very close (for LVDS etc). The above suggest this is not the case. Can you please provide more information on the actual routing?
Thanks,
Mike
