DAC to FPGA compatibility

Hi Sirs,

I start a new discussion to try to clarify some doubts with your help. To summarize, I am working with a xilinx fpga (zynq ultrascale+ mpsoc) and I want to connect an DAC evaluation board to use as a wave generator. It is the first time that I work with a dac and this type of fpga. The DAC has to have 14/16 bits resolution, minimum sample rate of 100MSPS, two channels and serial interface.

On your website, I have looked at models like AD9117, AD9747, AD9783 and AD9788, but I don't know if these models are compatible with my fpga model. 

To know if they are compatible I have to look at the supply voltage of the bank to which it will be connected, if I can generate the dac sampling clock, I/O voltages VIH, VIL, VOH, VOL.

Am I going in the right direction?

Any help is appreciated.

Thanks in advance.


  • Hi,

    You are definitely going in the right direction.

    Make sure that the FPGA can operate at your desired DAC data clock and check if VIH and VIL specs of the DAC are compatible with your FPGA's VOH and VOL specifications at the digital supply voltage of operation.

    Take note that the devices you listed above have different data interfaces. AD9117, AD9747, and AD9788 have CMOS data interface while AD9783 has LVDS. The evaluation boards of all these devices are compatible with SDP-H1 so you may compare the specifications of your FPGA to the one in this board. You may also visit the evaluation board web pages of the said devices to see how clocking is implemented and how pin assignments of the connectors to the FPGA board are planned or designed.


  • Hi Shine,

    Thanks for your answer. 

    I will review everything you have answered me and if I have any questions I will reply again.
