Hi everybody , I am looking for a development board. My intention is to devolp a DSP application so ideally should contain : -xc3s500e-pq208 -ADC <80Msps <10bit -DAC same specifications. -The PROM and JTAG interface is not an issue . I have a JTAG programmer for PROMS. I would reaaly appreciate your help. Alfredo Taddei

I need at least 80 Msps and 10 bit resolution. I apologize for the inconvenience. Alfred

You might have to replace the FPGA xc3s200-pq208 with the xc3s500e-pq208 you asked for. Dunno if they're pin compatible... DC851A DC890B Syms.

Alfredo 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.

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. Best Regards, Alfredo Taddei
