Table 4–88. Stratix II GX Maximum Input Clock Rate for Column I/O Pins (Part 1 of 2)
I/O Standard
-3 Speed Grade
To calculate the output toggle rate for a non 0 pF load, use this formula:
The toggle rate for a non 0 pF load
For example, the output toggle rate at 0 pF load for SSTL-18 Class II
20 mA I/O standard is 550 MHz on a -3 device clock output pin. The
derating factor is 94 ps/pF. For a 10 pF load the toggle rate is calculated
as:

= 1,000 / (1,000/ toggle rate at 0 pF load + derating factor × load
value in pF /1,000)
1,000 / (1,000/550 + 94 × 10 /1,000) = 363 (MHz)
