thanks for links, will check them.

Exactly this is my idea. The PCB routing using either FMC or HSMC is not 
a big deal. Even if we could set the standard for the connector used by 
the FPGA developers community, then it would be easy to develop 
HSMC->FMC or FMC->HSMC connector board. The question is if we could just 
copy the USRP(2) hardware to the FMC/HSMC board or use other ADC/DAC 
devices? I am not sure why such particular hardware was selected for 
USRP, but it is possible to buy better for the same price. Ok, I may 
exclude TxDAC+ from AD, which has some more advantages over a simple 
DAC, but that's it. I've just purchased DAC3283 (16bit/800MSPS) from 
eBay:

so I will try its performance later.
