The description of the FMC700 is, "The FMC700 is an adapter that connects to the KC705 LPC and HPC FMC sites in order to offer a HPC FMC site as close as possible to ANSI/VITA 57.1."
What specific discrepancies between the KC705 HPC FMC site and ANSI/VITA 57.1 does the FMC700 fix?

Dear Sir,
On the KC705, Xilinx decided to not route HPC connector's bank HB. Therefore it is not compliant to Vita. As per the Vita specification, a full blown HPC FMC connector requires all the bank to be routed to the CPU/FPGA (HA, LA and HB).
FMC700 does provide a fully HA, HB and LA using both LPC and HPC connectors on the KC705.
FMC-HPC has many pin and you need an FPGA with a lot of IOs to have everything connected and typically the FPGA on the KC705 is an FPGA without much IO/s.
I hope that helps!
Best Regards,
Arnaud

Thanks, that answers my question and helps. I have a follow-up question for the FMC125/FMC700 here (http://www.4dsp.com/forum/index.php/topic,3586.0.html), though.
