DAC38J84EVM: DAC to Xilinx KCU105 using JESD204B via FMC

Part Number: DAC38J84EVM
Other Parts Discussed in Thread: DAC38J84, ADS42JB69EVM, , DAC38RF82

I am working on getting KCU105 (www.xilinx.com/.../ug917-kcu105-eval-bd.pdf) to talk to the TI DAC38J84 (www.ti.com/.../dac38j84evm) with JESD via FMC.  I have JESD IP for the FPGA and both boards have FMC.  

Seemed simple enough, but I recently found this weird FMC to FMC board (www.ti.com/.../slau580b.pdf).  I don't understand the purpose of this board and most importantly if it is a hard requirement for communication.  Additionally, this FMC to FMC board and the Xilinx firmware that comes along with it look like they only support up to the old Xilinx FPGAs, not the KCU105.  Is there a newer version?  

According to Xilinx this DAC should be compatible with the KCU105.  For reference the TI ADS42JB69EVM (www.ti.com/.../ads42jb69evm) can definitely connect without the FMC to FMC board as written under features and in this report (www.ti.com/.../slal212.pdf).  What I am really looking for is the Xilinx firmware to interface KCU105 with the DAC84J38 directly, similar to the Xilinx firmware listed under the FMC to FMC board.  

I would greatly appreciate some clarification. Thanks so much!

    5078.KCU105 HSDC Pro User's Guide.pdfMason,

    You can plug the DAC38J84EVM directly into the KCU105. The other FMC board is only used with the KC705, VC707, and ZC706. Please see the attached file for more information.

    Regards,

    Mason,

    We have an example of the DAC38RF82 interfacing to the KCU105 in our newly released document titled “HSDC Pro with Xilinx KCU105”, which is attached. This document can be downloaded from the HSDC Pro GUI product folder on the TI website. Due to the fact the user cannot program the FPGA through a JTAG connector on the KCU105, the interposer board (TSW14J10EVM) is not needed for this interface. The customer must use Vivado though, to program the provided compiled firmware that comes with the latest version of HSDC Pro.      

     

    If a customer is creating their own interface firmware, an example can be found on the Xilinx website. Send them to the Xilinx JESD204 lounge and get them to download the file shown below:

     

    http://www.xilinx.com/member/jesd204_eval/JESD204B_UltraScale_Hardware_Demo_2016_1_v1.3.zip

     

    By default this will build a hardware loopback demo. But if they run the command set TARGET “TI” before running the build_it.tcl script, it will build the demo for TI EVM’s. More information can be found in the attached pdf from Xilinx.

     

    Regards,

    Thank you so much! I really don't know how I didn't see this anywhere.
