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?
