Something in this vein is our Broaddown2 product which we have been
using with a high performance Linear Tech ADC eval module recently.
The eval module we have been playing with nearly straight plugs into
our edge connector on this poduct.

Details of BD2 here http://www.enterpoint.co.uk/moelbryn/broaddown2.html.

With some lashing up quite of a number of our products could used with
eval modules from the likes of Linear Tech. We have lots of
uncommitted pins and bank voltage selection in various of our
products.

Longer term we may have a product, maybe more, that meets your entire
requirements but I can't possibly talk about these quite yet.

I came to the same conclusion by now.  I found a 'piggy back' module
carrying two A/D and two D/A converters 12 bit@200MSPS [1], maybe I can
combine this with an FPGA board type that you mention.

The system does not really not to be low cost (I'm not a student),
but I assume a board with a Virtex II device [2] with 1 million gates is too large for me.

100 MSPS @ 12 bits is a little out of the ordinary for a low-cost FPGA
board.  I'd suggest looking for an FPGA board with sufficient I/O
connections and cobble the system together with an A/D converter
board (if you can find that - perhaps an evaluation module from the
converter manufacturer?).

I'm looking for a (low-cost) spartan 3 based board, containing a
low to medium sized spartan 3 fpga, two 100 MSPS 12 bit AD converters,
and ideally also one or two 8-12 bit DA converters, but I didn't find any.

Does someone know of such a board?

Thanks,
Thomas
