Does IBUFDS_DIFF_OUT with -DT option exist?

[qlyus]

IBUFDS_DIFF_OUT is a differential input clock buffer with differential
outputs. It is exampled in xapp622 for Virtex-II device. I would
guess the same primitive exists in Virtex-II Pro. But I want to use
it with -DT differential terminate. Does it exist? if yes, what is
the symbol name and how to use it (if different from the example in
xapp622)?

Thanks.
