Input Path
A buffer In the Virtex IOB input path routes the input signal
either directly to internal logic or through an optional input
flip-flop.
An optional delay element at the D-input of this flip-flop elim-
inates pad-to-pad hold time. The delay is matched to the
internal clock-distribution delay of the FPGA, and when
used, assures that the pad-to-pad hold time is zero.
Each input buffer can be configured to conform to any of the
low-voltage signalling standards supported. In some of
these standards the input buffer utilizes a user-supplied
threshold voltage, V
constraints on which standards can used in close proximity
to each other. See I/O
There are optional pull-up and pull-down resistors at each
user I/O input for use after configuration. Their value is in
the range 50 kΩ – 100 kΩ.
Output Path
The output path includes a 3-state output buffer that drives
the output signal onto the pad. The output signal can be
routed to the buffer directly from the internal logic or through
an optional IOB output flip-flop.
The 3-state control of the output can also be routed directly
from the internal logic or through a flip-flip that provides syn-
chronous enable and disable.
Each output driver can be individually programmed for a
wide range of low-voltage signalling standards. Each output
buffer can source up to 24 mA and sink up to 48mA. Drive
strength and slew rate controls minimize bus transients.
In most signalling standards, the output High voltage
depends on an externally supplied V

ing, page
An optional weak-keeper circuit is connected to each out-
put. When selected, the circuit monitors the voltage on the
pad and weakly drives the pin High or Low to match the
input signal. If the pin is connected to a multiple-source sig-
nal, the weak keeper holds the signal in its last state if all
drivers are disabled. Maintaining a valid logic level in this
way eliminates bus chatter.
Because the weak-keeper circuit uses the IOB input buffer
to monitor the input level, an appropriate V
be provided if the signalling standard requires one. The pro-
vision of this voltage must comply with the I/O banking
rules.
I/O Banking
Some of the I/O standards described above require V
and/or V
nected to device pins that serve groups of IOBs, called
banks. Consequently, restrictions exist about which I/O
standards can be combined within a given bank.
