Hi All,

I need to work with IQ modulation so I need to work with two DACs and

I would like know can we use two AD9739A-EBZ Evaluation Board with one Virtex-6 (ML605 EV board)?

If so, how to make synchronization of both DACs, please?

Bon

I had a similar question. I was told that the AD9739A came from the AD9739 with the synchronization logic taken out to improve the analog performance. The AD9739 still requires some minimal external logic to synchronize 2 devices.

As for the AD9739A, if you apply the same clock and data to both devices, the most they can be off is 4 cycles of the input clock due to a divide by 4 logic which drives the digital interface.
