TRF3722: specs in datasheet

PS: idem for TRF372017, Zi (baseband input impedance) specification outlined in data sheet’s page 5, does it  refer to differential or single ended ?

looking forward for a prompt answer

thnaks a lot in advance

hi Russell,

thanks. Just to be sure, root of the question relis on the mismatch between data on electrical table:

and fig.85 on pag. 33:

Which is the correct one?

thanks a lot in advance

Hi,

If it helps, I have the following measured on the DAC3484/TRF372017 interface guide

hi Kang,

So may we conclude that Rin=5K and Cin=3pF is the differential input impedance, correct ?

thanks a lot in advance

Vincenzo,

I meant the measurement I made in the app note are the same as Figure 85 of the datasheet.
