Notes to Table 3–19:
(1) Delay numbers for tGLOB differ for each device density and speed grade. The delay numbers for tGLOB, shown in Table 3–19, are based on a 5M240Z
device target.
(2) For more information about delay adders associated with different I/O standards, drive strengths, and slew rates, refer to Table 3–34 on page 3–24
and Table 3–35 on page 3–25.
(3) For more information about tXZ delay adders associated with different I/O standards, drive strengths, and slew rates, refer to Table 3–22 on
page 3–15 and Table 3–23 on page 3–15.
(4) For more information about tZX delay adders associated with different I/O standards, drive strengths, and slew rates, refer to Table 3–20 on
page 3–14 and Table 3–21 on page 3–14.
