64bit datawidth fot V6 GTX

V6 GTX will support 64bit datawidth?

 

For PCIE Gen3,if 32bit,the pipe clk needs at least 250MHz.I think it is impossible to archieve it unless 64bit datawidth.

PCI Gen3 runs at 8.0 Gb/s with 128B/130B encoding.  This is not possible with Virtex-6 GTX Transceivers.

The Virtex-6 GTH has a limited operating range as defined in the data sheet.  8.0 Gb/s is outside of that range.
