hi jonathan,
we expect roach boards will be about $2500 each, plus FPGA.
you'll need to add DRAM ($50 min), ATX enclosure ($100), and
ATX power supply ($50).
there are several ADC boards you can use, but only two ADC
board that can sample > 1 Gsps currently available:
a) the Atmel/E2V dual 1 Gsps, single 2 Gsps
b) the National dual 1.5 Gsps or single 3 Gsps
(you stuff with either ADC083000 or ADC08D1500)
you can interleave two of the national ADC083000 boards
to get 6 Gsps.
the south african's are working on another national ADC
board that will use same ADC, but it will have on board
programmable gain/attenuator, and optional frequency synthesizer.
we are also talking to agilent about using their 20 Gsps ADC.
best wishes,
dan

Can someone please advise rough numbers (which one might use in a
funding proposal), for the cost to fabricate, assemble and test Roach
PCBs? Please assume donated FPGAs, or break out their cost). This
application does not not use large volumes, so assume a run of say 10
boards.
Also, is there a roadmap for compatible ADC boards? In particular we
seem to recall discussion at the workshop of an ADC, with two input
channels *each* capable of sampling at a 2 GSa s^-1 rate, which connects
to a single ZDOC. Is this called iADC2? Has this been built yet? Is
there a rough estimate of cost to fabricate, assemble and test?
Thanks for any guidance the list can offer.
Regards, Jonathan
