DAC38RF80EVM: How to synchronize two DAC38RF80EVM boards?

I actually would like to achieve the following:

Case 1) Use an external DAC clk, split the clock to two DAC38RF80EVMs and trigger the waveform generation using an external trigger signal provided to J13 on both TSW14J56EVM.

Case 2) Use internal PPL generated DAC clk on one  DAC38RF80EVM, and provide that to the second DAC38RF80EVM. And then trigger the waveform generation using an external trigger signal provided to J13 on both TSW14J56EVM.

Hi Steve,

We are looking at your question and will get back to you soon.

Hi,

I tried to set up the two boards with two TSW14J56EVMs and provided a hardware trigger to both boards. It seems both DACs are triggered when J13 sees a rising edge. I actually was expecting the DAC would only be active when J13 is HIGH. Is there a way to modify the setting?

Thanks,

Steve

Steve,

The trigger works on a rising edge. What modification are you requesting?

Hi Jim,

Can it be modified to trigger ON on a rising edge, and trigger OFF on a falling edge?

Thanks,

Steve
