In the ASIC specification 1.3 you suggest the ASIC could drive the FADC directly. I have extracted some parts of the ADC datasheet concerning the input stage into a document and attach the full data sheet. Could you have a look and let me know if the ASIC can drive the FADC without buffering. The saving in power and layout etc is quite large, about 46W per FEE module.
