can we use ADC of 70-100MHz with dsp56303

hi,

i want to know, is it possible to use ADC of around 70-100MHz sampling frequency with the dsp 56303 by using the digital down converter in between the ADC and the DSP.

 since the ADC of such a sampling frequency come with the parallel output only and the dsp56303 will not support that. so by using the digital down converter can we process the output of ADC with DSP with out any loss of resolution of the signals.
