On the output variation of the AD9266

My customers are considering using AD9266.


So I got some questions.
When the input was short-circuited and internal Ref was used, about 0.1% noise was observed at the output.

(input· · · 2 Vp - p, noise · · · about 2 mVp - p)


# 1  Is there data that varies in output noise and output data when internal Ref and external Ref are used?


# 2  If the exposed ground pad's GND connection is made with fewer vias, will the output variations become larger?   (Currently 4 vias)


# 3 Is there any other reason why the output noise and the variation of the output become bigger?


Best Regards,
