At which resolution do you wish to get 40Msps? Tell me the single-shot 
jitter figure. So far we had only several ksps of throughput in our TDC 
circuit, but the bottleneck lies within a computer interface.

Anyway, it is not an easy task to get some 200MB/s into the computer in a 
sustained fashion. (And to process such amounts of data in real time is 
hard, too.)
