I have a Virtex 7 evaluation board.
I want to connect some LVDS pairs to my board via the 2 HPC FMC bank.
Is it possible to do so ?
I've seen on the datasheet only LVCMOS 1.8V as a protocol for I/O ..
I also have some signals LVTTL 3.3V. As I can see on the datasheet, the voltage requirement for HP bank is 1.8V, I guess I have to convert my signals LVTTL 3.3V <-> LVCMOS 1.8V ?
Thanks for yours answers and happy new year !

Ok I found part of my solution.
If I'm not mistaken, there is no problem if I want to connect my LVDS signals to FMC HPC of Virtex 7 eval board (according to the datasheet).
Just have to check if it accept 250 MHz signals ?
Still, I'm still looking for a solution to convert my TTL 5V signals I/O to communicate with my FPGA board. Apparently, I can't send LVTTL 3.3V to FMC HPC but only LVCMOS 1.8V ? Could someone clarify me all my wonders ?
Thanks a lot and Happy new year to everyone !!
