Table 5–44. Maximum Input Clock Toggle Rate on Cyclone II Devices (Part 1 of 2)
I/O Standard
For example, the output toggle rate at 0 pF (default) load for SSTL-18
Class II 18mA I/O standard is 270 MHz on a
The derating factor is 29 ps/pF. For a 10pF load, the toggle rate is
calculated as:

= 1000 / (1000/toggle rate at default load + derating factor * load
value in pF/1000)
1000 / (1000/270 + 29 × 10/1000) = 250 (MHz)
