But, How hard IP assigment the I/O (Qsys make me a entity of interface) to pins???
When I see the interface I only see one Tx and Rx......the pin planer I see two Rx and Tx (diff pairs).
How can I assign one Tx and Rx (I/O of entity make bye Qsys) to two Tx and Rx of pin Planer???

You only need to assign the pins in your top-level port list to the + pins of the diff pairs. The Pin Planner automatically creates and assigns the - pins (they show up as your port names with (n) appended).
Sometimes I wish Altera just stuck with the physical representation of diff pairs instead of hiding the details. It does get confusing at times.
