I mean this toy will work


I'm willing to accept some tradeoffs for the sake
of simplifying the design (i.e. the AD9874 integrates
an ADC and digital filter which is convenient though
less flexible then a ADC coupled with a FPGA).

however the performance of the classic analog
receiver of the communication class is much better.


That seems to imply some type of fundamental limitation
exists with using the AD9874. Care to be more specific?
For example the AD9874 spec claim 95 dB dynamic range,
there are certainly radios which claim a higher dynamic
range. However I'm imagining that a 95 dB dynamic range
should work for a lot of signals.
