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 ? thks

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

--- Quote Start ---

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.
