1) The phase relationship of C4i and C16i depends on the user’s timing source (see Fig. 13 for device related contstraints).
2) Timing measurements for inputs are referenced to/from a low voltage of 0.8V and a high voltage of 2.0V.
Measurements for outputs are referenced to/from a low voltage of 0.4V to a high voltage of 2.4V
