External timing parameters are specified by device density and speed grade. All
external I/O timing parameters shown are for the 3.3-V LVTTL I/O standard with the
maximum drive strength and fast slew rate. For external I/O timing using standards
other than LVTTL or for different drive strengths, use the I/O standard input and
output delay adders in
For more information about each external timing parameters symbol, refer to the
