FG680 Differential Pin Pairs
Virtex-E devices have differential pin pairs that can also pro-
vide other functions when not used as a differential pair. A
√
in the AO column indicates that the pin pair can be used as
an asynchronous output for all devices provided in this
package. Pairs with a note number in the AO column are
device dependent. They can have asynchronous outputs if
the pin pair are in the same CLB row and column in the
device. Numbers in this column refer to footnotes that indi-
cate which devices have pin pairs than can be asynchro-
nous outputs. The Other Functions column indicates
alternative function(s) not available when the pair is used as
a differential pair or differential clock.
