Honored ContributorALT_INBUF_DIFF in cycloneII
is possible in cycloneII device use 2 pins INPUT for differential rs422 signal? In quartus2 the differential buffer for cyclone2 is not allowed!

in my case it is a "modified" rs422. it works at 0-3.3Volt. see max13433 http://datasheets.maxim-ic.com/en/ds/max13430e-max13433e.pdf can lvds pin work at 3.3 volt?
