The reference points for the rise and fall transitions are measured at VIL MAX and VIH MIN.
M = the PLL multiplier factor (x4, x6, x7, x8, x9, x10, or x11). For more details, see the clock PLL section of this data sheet.
§C = CLKIN cycle time in ns. For example, when CLKIN frequency is 50 MHz, use C = 20 ns.

When the 5-V PCI clamp is used, the reference points for the rise and fall transitions are measured VILP MAX and VIHP MIN for 5 V operation.
When the 3.3-V PCI clamp is used, the reference points for the rise and fall transitions are measured at VILP MAX and VIHP MIN for 3.3 V
operation.
