4.9.1.5. FMC Loopback Card
The Intel® Stratix® 10 GX FPGA development kit provides one FMC mezzanine interface port connected to the Intel® Stratix® 10 GX FPGA for interfacing to the Intel FMC add-in boards as shown in the figure below.
The FMC interface is mechanically compliant with the Vita57.1 specification for attaching a single width mezzanine module. However, in terms of signal connections, the Intel
FMC interface is not fully compliant with the Vita 57.1 specification. Instead, it contains a subset of the Vita57.1 interface signal to the connector as shown in the FMCA signal assignment tables.The following table shows the complete signal connections assigned for Intel FMC interface at the FMCA port.
