Looking for a development board

Thanks , I did a quick research and couldn't find anything with the ADC and DAC I need. It looks like there aren't these kind of boards around. At least if I could get a footprint it would really help.

From your original post, what do you mean by "-ADC

Nope, not at all;

Cheers,

I'm not sure you will find a product like this. Most of the DSP orientated boards with ADC/DAC at this level tend be lined up with Virtex level FPGAs.

I would also make the observation that the PQ208 package relatively poor at handling high speed I/O compared to BGA based parts and if we were designing a development board of this specification we certainly would not be using the PQ208 package.

Not quite what you want and not a pretty solution but some of the Linear Tech ADC demo boards can plug into our Broaddown2 Spartan-3 Development, with minor mods, on the edge connector Alternatively you might also to be able to wire something like our Drigmorn1/Craignell boards (fitted with either XC3S100E-4CPG132C or XC3S500E-4CPG132C) on a high quality breadboard together with Linear Technology boards.

Longer term we do have plans for middle end ADC/DAC modules to support all of our products that have DIL headers on them and for the very high end ADC/DAC there will be a Moel-Bryn module/s and another format(to be announced) that will support the forthcoming Hollybush2 product.

Yes John, you are absolutely right. There is no such a product like the one I am looking for. I give up. All the boards you suggested , were already visited.The project is meant to implement two IIR filters( with programable coeffs) in one of these spartan3 , and it doent require high-speed(25Mhz) but low-cost , and thispackage is easier to mount (according to what I heard). We will have to develop our own board.I am skilled at programming VHDL for DSP specially , so I will have to ask a PCB designer here in my company to do the wok for me. Thanks folks for the valuable information you share in this group.
