Symbol
These timing parameters are sample-tested only.
These timing parameters are for column IOE pins. Row IOE pins are 100- to 250-ps slower depending on device
and speed grade and whether it is t
for any pin.

Figure 6–6. External Timing in Stratix GX Devices
All external I/O timing parameters shown are for 3.3-V LVTTL or
LVCMOS I/O standards with the maximum current strength. For
external I/O timing using standards other than LVTTL or LVCMOS use
the I/O standard input and output delay adders in
6–76.
