Hi,

 

in my project I am using an ADL5380 for demodulating RF signals. I only need one of the in-phase outputs for further signal processing.

Because I am more or less a newbie to this field, my questions now are the following:

 

1:   

Can I leave the unused ouput pair floating or should it be terminated?

 

2:

How to properly terminating the unused output of the used signal pair? Is a simple solution like coupling it to ground through a cap recommended or can i leave it floating? (I've tried the floating option and so far it would fullfil my needs, but this seems not the right approach from an engineering point of view)

 

Thanks paku
