ADS52J65: filter taps normalization

Tool/software:

Hi

I want to simulate the ADS52J65 converter chain with a fixpoint model to evaluate the possibilities of the downconverter and decimator. Is there any constraints of the filter taps loaded to the coefficient RAM such as normalization? What would be the fixpoint representation of these coefficients (sign, 0 integer, 13 fractional bits)?

Thanks

Daniel
