ad9266

Hi,

I'm designing a digitizer based on AD9266-20. It will be transformer coupled, with a 3rd order differential ellittic filter placed between

transformer output and adc input (anti-aliasing).

To correctly design the filter I need to know how to model the input impedance of the AD9266. In the datasheet it

is reported 6.5 pf, but not the resistive value.

Can you help ?

thanks
