Part Number: DAC5674EVM
As stated in the title I'm attempting to generate a sawtooth wave with an Artix-7 FPGA. I'm driving the DAC with a single-ended clock, and have followed the instructions for the single-ended clock configuration in the module's datasheet. Unfortunately, I'm not seeing anything on the output pins. I've verified that the data and clock from the FPGA are correct, as is the PLLLOCK indicator from the chip. I'm hoping to talk to an engineer so that we can get this sorted out.
Thanks a bunch,
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

I've returned to this post to add some additional information. Attached are some oscilloscope screen grabs, the first being the external clock signal and the second being the PLLLOCK signal. I've also attached a spreadsheet where I tested each pin status on the DAC chip and tested them against my assumptions. Maybe someone can identify an error in my configuration on the bench?
Thank you very much,

My clock rate is 1kHz, the datarate is ~340Hz, and the interpolation mode being used is 2x interpolation.
