xilinx MGT compatibility?

Hi,

 can the MGT of Virtex-4FX talk to the
MGT of Virtex-2Pro (XC2VPX) ?
Any experience or problems ?

Howdy Tullio,

The FX parts with MGT's haven't even been released to engineering (or
early) sample yet, so nobody is going to have experience with them yet
except Xilinx.  Regardless, there should be no problems getting the
MGT's of the two parts (or most any other devices with a SERDES,
including Altera's Stratix GX) talking to each other, provided you
choose a bit rate that is supported by both devices.  For example, make
sure to have a -7 speed-grade V2Pro if you want to do 3.125 Gbps.

Have fun,
