I tried to calculate the right DCLKIN values with the ADC35XX GUI 1.0 (or ADC3660EVM GUI, as it is also called).
The calculated DCLKIN values seem to be right for BYP or decimation factors up to 8.
For decimation factors of 16 and 32, only garbage numbers appear as results for DCLKIN (MHz) in the dialog window:
Is there a simple formula for calculating the DCLKIN frequency by myself, i.e. without using the GUI?
