True LVDS - Stratix IV

Hi, 

I use an EP4SE820 device with 1760 pins. 

Can you confirm that the bank 1,2,5,6 have true LVDS I / O ? 

If this is the case, it is not necessary to add resistors ?

Another question, can you confirm that it is possible to supply VCCIO to 3.3v ?

The device handbook doesn't list 3.3V as supported VCCIO level:

You can connect the VCCIO pins to a 1.2-, 1.5-, 1.8-, 2.5-, or 3.0-V power supply, depending on the output requirements.

The 3.3-V LVTTL and 3.3-V LVCMOS are supported using VCCIO and VCCPD at 3.0 V.
