How to generate 8.192MHz clock on labview FPGA 7854R series card?

[Work_Study]

Hi,

   I am using NI PXI-7854R series card which has Xilinx Vertex 5 FPGA on it. I am trying to derive a clock of 8.192 MHz from the 40MHz on board clock of FPGA. But it ends up giving me only 8MHz clock. Is there any way of accessing the PLL which is on Xilinx FPGA?

Regards

If you are familliar with VHDL you can make your own "Component Level IP" (aka CLIP) with a Xilinx PLL inside.  There are topics in the help and examples showing how to define a CLIP.  Here is one that shows how to instantiate a DCM (similar to a PLL) in a CLIP:
