AD9608 IF upper limit

Dear Sir:


We would like to use AD9608 at 110M Rate to sample IF frequency equal to 191MHz.  The IF signal is wide band with 34M Bandwidth.


Base on under-sampling theory, the signal will be mapped to 12M to 46MHz.


However, the upper IF frequency is 191M + 17M = 208MHz, it exceeds the recommended 200MHz IF frequency in the AD9608 datasheet.

Will this scheme work with AD9608?  Any comments on this application?


Thank you very much.
