[10GBASE-T] Re: [10GBT-Modeling] A question list we need to answer


Your list of questions is good. However, since this is feasibility
study we have to also keep some high-level implementation issues in mind. 
Among them would be analog front-end's linearity, ADC's quantization 
noise, ADC's jitter-limited ENOB etc.
