DSP development board with fast A/D

Started by dohm February 15, 2006
I am looking for a DSP development board for a bench-top project. I want to
use an Analog Devices Sharc or equivalent TI processor. My input signal of
interest is a LFM waveform with a 30MHz bandwidth (Lets assume it is at
baseband for now). So, I would like to find a development board with dual
A/D converters that sample > 30Msps. It would also be interesting to know
if any development boards are available with A/Ds that sample at >60Msps.
My search at this point is somewhat generic so I am not worried about the
details yet. I just want to know what development board options are out
there that are not designed for the usual audio applications.

I noticed that Analog Devices has some extender board options for there
Sharc EZ kits. Has anyone used one of these with there faster A/D
evaluation boards? Does TI have more options? Any input or opinions are
appreciated.

Thanks!

Dave, we have our dspstak SHARC based boards that you can use in conjunction with our dspstak a9244 ADC board. The a9244 uses an ADI AD9244 sampling at 40 Msamples/s. The DSP is limited to 50M samples/s. We also have an extender similar to the ADI extender, that adapts ADC dev boards from ADI.
