Cyclone IV GXB vs dual-purpose differential transmitter/receiver channels

Hi

I just noticed that i was writing wrong. The "rx" side of GXB gives no problem in Quartus when assigenet as LVDS. Sorry about that.

I exported pin assigement in Quartus. Here is the pin definitions of signals in question

To,Direction,Location,I/O Bank,VREF Group,I/O Standard,Reserved,Current Strength,Slew Rate,Differential Pair
LVDS_CLK1_in,Input,PIN_E7,8A,B8_N0,LVDS,,,,LVDS_CLK1_in(n)
LVDS_CLK1_in(n),Input,PIN_E6,8A,B8_N0,LVDS,,,,LVDS_CLK1_in
LVDS_DATA0_in,Input,PIN_J2,QL0,,LVDS,,,,LVDS_DATA0_in(n)
LVDS_DATA0_in(n),Input,PIN_J1,QL0,,LVDS,,,,LVDS_DATA0_in
LVDS_DATA1_in,Input,PIN_E2,QL0,,LVDS,,,,LVDS_DATA1_in(n)
LVDS_DATA1_in(n),Input,PIN_E1,QL0,,LVDS,,,,LVDS_DATA1_in

for the "I/O Standard" you can see that i am using LVDS and Qv11.0 does not complain.

For the transmission over GXB i can use only 1.5 PCMA standard or 2.5V "default"
