Switching Characteristics
Periphery Performance
This section describes periphery performance and the high-speed I/O and external
memory interface.
I/O performance supports several system interfaces, such as the LVDS high-speed
I/O interface, external memory interface, and the PCI/PCI-X bus interface. GPIO
standards such as 3.3-, 2.5-, 1.8-, and 1.5-V LVTTL/LVCMOS are capable of a typical
167 MHz and 1.2 LVCMOS at 100 MHz interfacing frequency with a 10 pF load.

Actual achievable frequency depends on design- and system-specific factors. You
must perform HSPICE/IBIS simulations based on your specific design and system
setup to determine the maximum achievable frequency in your system.
High-Speed I/O Specification
