Stratix Device Handbook, Volume 2
3.3-V 2× AGP - Intel Corporation Accelerated Graphics Port
Interface Specification 2.0
The 2 AGP I/O standard is a voltage-referenced, single-ended standard
used for 3.3-V graphics applications. The 2 AGP input standard
specifies an input voltage range of – 0.5V V
standard does not require board terminations. Stratix and Stratix GX
devices support both input and output levels.
GTL - EIA/JEDEC Standard EIA/JESD8-3
The GTL I/O standard is a low-level, high-speed back plane standard
used for a wide range of applications from ASICs and processors to
interface logic devices. The GTL standard defines the DC interface
parameters for digital circuits operating from power supplies of 2.5, 3.3,
and 5.0 V. The GTL standard is an open-drain standard, and Stratix and
Stratix GX devices support a 2.5- or 3.3-V V
GTL requires a 0.8-V V

GTL+
The GTL+ I/O standard is used for high-speed back plane drivers and
Pentium processor interfaces. The GTL+ standard defines the DC
interface parameters for digital circuits operating from power supplies of
2.5, 3.3, and 5.0 V. The GTL+ standard is an open-drain standard, and
Stratix and Stratix GX devices support a 2.5- or 3.3-V V
standard. GTL+ requires a 1.0-V V
