Hello.

 

When I don't use Reference B, how to terminate Reference B?
In Datasheet Differential Input Resistance is 5kohm.

If I terminate the Reference B short to GND or resistance to GND,  I concerned about an effects that come out to Reference A.

Reference A input condition is single end, 10MHz, AC coupled and 1V DC bias.

 

Which is Optimally GND termination, Open, resist termination?

 

Best regards.
