LVPECL with VCC of 3.3V on a Cyclone3

Hi, Is it possible to use LVPECL signals on a bank that has VCCIO = +3.3V? I am using a Cyclone3 part. Thanks

I need LVPECL inputs. My only available banks have VCCIO of 1.8V and 3.3V. I am using a LMH7322 as a driver which provides PECL and LVDS outputs. Is there a way to level shift a LVPECL or LVDS signal to SSTL_18 so it can be used on the 1.8V bank?
