Figure 38. External Timing in Cyclone Devices
All external I/O timing parameters shown are for 3.3-V LVTTL I/O
standard with the maximum current strength and fast slew rate. For
external I/O timing using standards other than LVTTL or for different
current strengths, use the I/O standard input and output delay adders in
