Setting AD9144 SPI Pro Quick Configure refClk, Fin, and FDAC frequencies register values

I am working with the FMCDAQ2 board with the Xilinx ZCU102 using hdl and no-OS Xilinx 2017.1 branch.  I would like to have the AD9144 run at a much higher rate than what the fmcdaq2.c software menu offers.  Since I am sending out a 800MHz sine wave, I need the AD9144 to run at least 2GHz.  To do this I have to set the DAC PLL and interpolation registers.  I am rather clueless as to what my register setting should be.  I was hoping the DAC Software Suite AD9144-EBZ SPI Pro could output register values for me.

  1. When I look at the AD9144 data sheet, it is not clear what refClk, Fin, and FDAC should be set to.
  2. I was hoping that if I hit the "Configure DAC only" button, that it would output the values and register addresses in a spreadsheet.  Then I would take that information and modify my fmcdaq2.c code.  But I don't see any output.

Regards,

Craig
