Eric,

The sampling rate will be 170 Msps. And the latency needs to be less tha
50 microseconds. When we began this project the idea was to use an Analo
Devices ADC (AD9430, 12 bit), followed by an FPGA and and then a DAC.
However in order to speed things up I was wondering if there wer
development kits available with all these components on one board.

Thanks!
Kevin
