FMCOMMS8 and Clocks on the FMC Connector

Product Number: FMCOMMS8

We are looking at using the FMCOMMS8 with a host board made by Alinx. After inspecting the schematics for the FMC HPC connector, we have observed one issue. We are wondering if this is a problem.

Here is a small section from the schematic for the FMCOMMS8

The host boards we are considering, do not have a connection for K4 or K5 on the FMC. Is this a problem? The host boards do have connections for J2 and J3.

Thanks,

Don

Hi Don,

sorry for the late reply.

From what I can tell those pins (K4/K5) are not used in the ZCU102/FMCOMMS8 reference design. See the constraints file.

Thank you,

Laszlo
