Chip-Wide Reset (Dev_CLRn) Specifications
Table 1–41 lists the specifications for the Stratix IV chip-wide reset (Dev_CLRn). This
specifications denote the minimum pulse width of the Dev_CLRn signal required to
clear all the device registers.
Periphery Performance
This section describes periphery performance, including 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.
General-purpose I/O standards such as 3.3-, 2.5-, 1.8-, and 1.5-LVTTL/LVCMOS are
capable of typical 167 MHz and 1.2 LVCMOS at 100 MHz interfacing frequency with
10 pF load.
For the Stratix IV GT –1 and –2 speed grade specifications, refer to the –2/–2× speed
grade column. For the Stratix IV GT –3 speed grade specification, refer to the –3 speed
grade column, unless otherwise specified.
1 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
Table 1–42 lists the high-speed I/O timing for Stratix IV devices.
