Low Voltage Differential Signals
The Virtex-E family incorporates low-voltage signalling
(LVDS and LVPECL). Two pins are utilized for these signals
to be connected to a Virtex-E device. These are known as
differential pin pairs. Each differential pin pair has a Positive
(P) and a Negative (N) pin. These pairs are labeled in the
following manner.
where
I/O pins for differential signals can either be synchronous or
asynchronous, input or output. The pin pairs can be used for
synchronous input and output signals as well as asynchro-
nous input signals. However, only some of the low-voltage
pairs can be used for asynchronous output signals.
DIfferential signals require the pins of a pair to switch almost
simultaneously. If the signals driving the pins are from IOB
flip-flops, they are synchronous. If the signals driving the
pins are from internal logic, they are asynchronous.

low-voltage pin pairs in the Virtex-E family.
Virtex-E Package Pinouts
The Virtex-E family of FPGAs is available in 12 popular
packages, including chip-scale, plastic and high heat-dissi-
pation quad flat packs, and ball grid and fine-pitch ball grid
arrays. Family members have footprint compatibility across
devices provided in the same package. The pinout tables in

Pin Name
Represents a general IO or a
synchronous input/output
differential signal. When used
as a differential signal, N
means Negative I/O and P
means Positive I/O.
Represents a general IO or a
synchronous input/output
differential signal, or a
part-dependent asynchronous
output differential signal.
Represents a general IO or a
synchronous input/output
differential signal, or an
asynchronous output
differential signal.
Represents a general IO or a
synchronous input/output
differential signal, a differential
clock input signal, or a DLL
input. When used as a
differential clock input, this pin
is paired with the adjacent
GCK pin. The GCK pin is
always the positive input in the
differential clock input
configuration.
