Are they really upsampling?
I was under the impression that they use one fast converter (far faster then
the sampling rate you hear) and the (de-)multiplex the signal to the various
channels. Should be easier than syncing several converter clocks.
The devices I work with on the other hand go exactly the other way, they
combine several 1GS/s adc's to have one 4GS/s adc. But they face their own set
of clock-sync problems...
