eval-ad9779a single ended vs differential output

Hello,

I was reading the documentation and I can't seem to figure out if there's a way to have a differential output on the EVAL-AD9779A card. According to docs, outputs are J4 and J8 but there are also J5 and J7 which are the N parts of the output. I want to maximize the span without needing to amplify my output

Thank you
