AD9915 Output Termination

Possibly silly question, but the built in 50 ohm pullups to AVDD on the AD9915 output can be considered part of the output termination, yes? So I can just go into a 100 ohm line to line resistor and then my 1:1 transformer (with center tap to AVDD)? Image attached. The 50 ohm ressitors are inside the AD9915.




Just never used a current sink output with built in pullups. I see the eval board has the external pullups marked DNI, but wanted to double check before committing to hardware.
