Notes:
1.
Input waveform switches between VL and VH.
2.
Measurements are made at typical, minimum, and maximum VREF values. Reported delays reflect worst case of these measurements. VREF values
listed are typical.
3.
Input voltage level from which measurement starts.
4.
This is an input voltage reference that bears no relation to the VREF / VMEAS parameters found in IBIS models and/or noted in Figure 4.
5.
The value given is the differential input voltage.
