[time-nuts] Really fast ADC needed

Fujitsu used to sell ultra-fast charge mode interleaved sampler (CHAIS)
ICs.
These have analog bandwidths of ~20GHz and sampling rates of 65 GS/s, 8-bit
resolution, with ENOB 5-6.

They pipe data out at  a max 128 bit* 500MHz (8 GB/s). How are you planning
to digest this data stream?

Regards,
Sebastian
