Dear Sir/Madam,

 

We have a question about AD9204 & AD9231 High Speed ADCs. (both BCPZ-40)

We would like to know the analog input circuit which acquired the AC SPECIFICATIONS on the data sheet.

There is specification at fin=200MHz.

 

Our usage.
Fin:200MHz
CLK:32MHz

 

Pls refer to the schematic from Evaluation Board User Guide(UG-003). below,

May I think that the AC SPECIFICATIONS(up to 200MHz) was acquired in this circuit? .

 

There is following description at page5 .below,

-AD9269 Family
-For the AD9269 family, the default analog input configuration supports analog input frequencies of up to ~150 MHz (see Figure 5).

It would be greatly appreciated if advice could be gotten.

 

Best Regards,
Kou
