You shoudn't have any problems, and don't have to do anything special besides assigning the pins.

For transceiver designs, I strongly recommend not designing by datasheet. Be sure to make a shell design with transceivers, the correct pinouts, pin location and standard assignments etc. and make sure it compiles before going to board layout. Quartus catches issues much better than trying to figure it out from the datasheet. Also, this isn't wasted work, since that shell will be used in the real design. It's far too easy to make a mistake and not know about it without this check.
