standard requires a Differential Amplifier input buffer and a
Push-Pull output buffer.
SSTL3 — Stub Series Terminated Logic for 3.3V
The Stub Series Terminated Logic for 3.3 V, or SSTL3 stan-
dard is a general purpose 3.3 V memory bus standard also
sponsored by Hitachi and IBM (JESD8-8). This standard has
two classes, I and II. SelectI/O devices support both classes
for the SSTL3 standard. This standard requires a Differential
Amplifier input buffer and an Push-Pull output buffer.
SSTL2 — Stub Series Terminated Logic for 2.5V
The Stub Series Terminated Logic for 2.5 V, or SSTL2 stan-
dard is a general purpose 2.5 V memory bus standard
sponsored by Hitachi and IBM (JESD8-9). This standard
has two classes, I and II. SelectI/O devices support both
classes for the SSTL2 standard. This standard requires a
Differential Amplifier input buffer and an Push-Pull output
buffer.
CTT — Center Tap Terminated
The Center Tap Terminated, or CTT standard is a 3.3 V
memory bus standard sponsored by Fujitsu (JESD8-4).
This standard requires a Differential Amplifier input buffer
and a Push-Pull output buffer.
AGP-2X — Advanced Graphics Port
The Intel AGP standard is a 3.3 V Advanced Graphics
Port-2X bus standard used with the Pentium II processor for
graphics applications. This standard requires a Push-Pull
output buffer and a Differential Amplifier input buffer.
LVDS — Low Voltage Differential Signal
LVDS is a differential I/O standard. It requires that one data
bit is carried through two signal lines. As with all differential
signaling standards, LVDS has an inherent noise immunity
over single-ended I/O standards. The voltage swing
between two signal lines is approximately 350 mV. The use
of a reference voltage (VREF) or a board termination voltage
(VTT) is not required. LVDS requires the use of two pins per
input or output. LVDS requires external resistor termination.
BLVDS — Bus LVDS
This standard allows for bidirectional LVDS communication
between two or more devices. The external resistor termi-
nation is different than the one for standard LVDS.
LVPECL — Low Voltage Positive Emitter Coupled
Logic
LVPECL is another differential I/O standard. It requires two
signal lines for transmitting one data bit. This standard
specifies two pins per input or output. The voltage swing
between these two signal lines is approximately 850 mV.
The use of a reference voltage (VREF) or a board termina-
tion voltage (VTT) is not required. The LVPECL standard
requires external resistor termination.
Library Symbols
The Xilinx library includes an extensive list of symbols
designed to provide support for the variety of SelectI/O fea-
tures. Most of these symbols represent variations of the five
generic SelectI/O symbols.
IBUF (input buffer)
IBUFG (global clock input buffer)
OBUF (output buffer)
OBUFT (3-state output buffer)
IOBUF (input/output buffer)
IBUF
Signals used as inputs to the Virtex-E device must source
an input buffer (IBUF) via an external input port. The generic
Virtex-E IBUF symbol appears in Figure 37. The extension
to the base name defines which I/O standard the IBUF
uses. The assumed standard is LVTTL when the generic
IBUF has no specified extension.
The following list details the variations of the IBUF symbol:
IBUF
IBUF_LVCMOS2
IBUF_PCI33_3
IBUF_PCI66_3
IBUF_GTL
IBUF_GTLP
IBUF_HSTL_I
IBUF_HSTL_III
IBUF_HSTL_IV
IBUF_SSTL3_I
IBUF_SSTL3_II
IBUF_SSTL2_I
IBUF_SSTL2_II
IBUF_CTT
IBUF_AGP
IBUF_LVCMOS18
IBUF_LVDS
IBUF_LVPECL
When the IBUF symbol supports an I/O standard that
requires a VREF, the IBUF automatically configures as a dif-
ferential amplifier input buffer. The VREF voltage must be
supplied on the VREF pins. In the case of LVDS, LVPECL,
and BLVDS, VREF is not required.
