Switching Characteristics
f For more information about the supported maximum clock rate, device and pin
planning, IP implementation, and device termination, refer to Section III: System
Performance Specifications of the External Memory Interfaces Handbook.
1 Actual achievable frequency depends on design- and system-specific factors. 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 Specifications
Table 1–31 through Table 1–36 list the high-speed I/O timing for Cyclone IV devices.
For definitions of high-speed timing specifications, refer to “Glossary” on page 1–37.
