As far as I know, the decimation is after the ADC, so ADC rate doesn't change
after changing the clock rate.  I'm happy to be corrected if it's not so. :)



That's correct. The ADC rates are fixed across all the products. That vastly simplifies things both in the FPGA
  DDC+CIC decimators, and the analog interface in front of the ADC.
