Fundamentals
Modern bus applications, pioneered by the largest and most
influential companies in the digital electronics industry, are
commonly introduced with a new I/O standard tailored spe-
cifically to the needs of that application. The bus I/O stan-
dards provide specifications to other vendors who create
products designed to interface with these applications.
Each standard often has its own specifications for current,
voltage, I/O buffering, and termination techniques.
The ability to provide the flexibility and time-to-market
advantages of programmable logic is increasingly depen-
dent on the capability of the programmable logic device to
support an ever increasing variety of I/O standards
The SelectI/O resources feature highly configurable input
and output buffers which provide support for a wide variety
of I/O standards. As shown in Table 18, each buffer type can
support a variety of voltage requirements.
Overview of Supported I/O Standards
This section provides a brief overview of the I/O standards
supported by all Virtex-E devices.
While most I/O standards specify a range of allowed volt-
ages, this document records typical voltage values only.
Detailed information on each specification can be found on
the Electronic Industry Alliance Jedec website at:
LVTTL — Low-Voltage TTL
The Low-Voltage TTL, or LVTTL standard is a general pur-
pose EIA/JESDSA standard for 3.3 V applications that uses
an LVTTL input buffer and a Push-Pull output buffer. This
standard requires a 3.3 V output source voltage (VCCO), but
does not require the use of a reference voltage (VREF) or a
termination voltage (VTT).
LVCMOS2 — Low-Voltage CMOS for 2.5 Volts
The Low-Voltage CMOS for 2.5 Volts or lower, or LVCMOS2
standard is an extension of the LVCMOS standard (JESD
8.-5) used for general purpose 2.5 V applications. This stan-
dard requires a 2.5 V output source voltage (VCCO), but
does not require the use of a reference voltage (VREF) or a
board termination voltage (VTT).
LVCMOS18 — 1.8 V Low Voltage CMOS
This standard is an extension of the LVCMOS standard. It is
used in general purpose 1.8 V applications. The use of a
reference voltage (VREF) or a board termination voltage
(VTT) is not required.
PCI — Peripheral Component Interface
The Peripheral Component Interface, or PCI standard spec-
ifies support for both 33 MHz and 66 MHz PCI bus applica-
tions. It uses a LVTTL input buffer and a Push-Pull output
buffer. This standard does not require the use of a reference
voltage (VREF) or a board termination voltage (VTT), how-
ever, it does require a 3.3 V output source voltage (VCCO).
GTL — Gunning Transceiver Logic Terminated
The Gunning Transceiver Logic, or GTL standard is a
high-speed bus standard (JESD8.3) invented by Xerox.
Xilinx has implemented the terminated variation for this
standard. This standard requires a differential amplifier
input buffer and a Open Drain output buffer.
GTL+ — Gunning Transceiver Logic Plus
The Gunning Transceiver Logic Plus, or GTL+ standard is a
high-speed bus standard (JESD8.3) first used by the Pen-
tium Pro processor.
HSTL — High-Speed Transceiver Logic
The High-Speed Transceiver Logic, or HSTL standard is a
general purpose high-speed, 1.5 V bus standard sponsored
by IBM (EIA/JESD 8-6). This standard has four variations or
classes. SelectI/O devices support Class I, III, and IV. This
