AD-FMCDAC2-EBZ with diff DACs outputs

Hello!

 

The AD-FMCDAC2-EBZ contains dual DACs AD9144  which  can  only work in the  first Nyquist zone. But outputs are AC-coupled and single-ended,  so they don't allow to connect wideband modulators.

I think developers should make the other version of the board with differential outputs.The standard SATA 7-pins connector, for example, could be used for differential interface of DACs.

Also, the RF transformers should be shielded.
