The proliferation of I/O standards and the need for higher I/O
performance have made it critical that devices have flexible I/O
capabilities. Stratix and Stratix GX programmable logic devices (PLDs)
feature programmable I/O pins that support a wide range of industry
I/O standards, permitting increased design flexibility. These I/O
capabilities enable fast time-to-market and high-performance solutions to
meet the demands of complex system designs. Additionally, Stratix and
Stratix GX devices simplify system board design and make it easy to
connect to microprocessors, peripherals, memories, gate arrays,
programmable logic circuits, and standard logic functions.
This chapter provides guidelines for using one or more industry I/O
standards in Stratix and Stratix GX devices, including:

Stratix and Stratix GX devices support a wide range of industry I/O
standards as shown in the Stratix Device Family Data Sheet section in the
Stratix Device Handbook, Volume 1 and the Stratix GX Device Family Data
Sheet section of the Stratix GX Device Handbook, Volume 1. Several
applications that use these I/O standards are listed in
3.3-V LVTTL/LVCMOS
2.5-V LVTTL/LVCMOS
1.8-V LVTTL/LVCMOS
1.5-V LVCMOS
PCI/CompactPCI
