I was wondering what anti-aliasing filter is need for the AD1974? The Datasheet shows the output sample rate but not the input sample rate.

Should I assume the input sample it is at the master clock frequency 256 x fs?

 

It appears that the input filter shown in the example may be all that is required but I'm not positive since I don't know the input sample rate.

 

Thanks
