FMC pcam adapter with ultrascale+

Question

Hey,

I'm using the VCU118 evaluation board with the Xilinx Ultrascale+ XCVU9P. I'm trying to connect to the FMC-pcam-adapter card. 

The MC20901 offers a SLVS to LVDS Conversion, so I can connect to the FPGA with LVDS and LVCMOS IO-STANDARDS.

I also have a CSI controller with a PPI interface. But, the Vivado's D-PHY IP can't have the HS(high-speed) and LP(lower-power) "split" into two differential pairs. 

Is there a way to use the Xilinx's D-PHY IP for ultrascale with the board ? or find a simple verilog connverter or DPHY ? 

Thanks,

-Gal

Two issues:

The pinout of the FMC Pcam Adapter might not support more than one Pcam when combined with an UltraScale FPGA: https://reference.digilentinc.com/reference/add-ons/fmc-pcam-adapter/reference-manual#fpga_io_architecture_compatibility. We are designing a new version of the adapter that improves UltraScale compatibility.

Secondly, Xilinx D-PHY IP expects D-PHY I/O standard for UltraScale+ architecture, not the split LVDS & LVCMOS that the adapter provides. One needs to modify the source code of the IP or edit the netlist to modify the input buffers. We are investigating this for the new version of the adapter and will provide more details here.
