Note:
1. All input specifications are measured from the midpoint voltage (1.4V) of the signal in question to the midpoint voltage of the rising edge of the input
L2SYNC_IN. Input timings are measured at the pins (see Figure 7).
2. Rise and fall times for the L2SYNC_IN input are measured from 0.4 to 2.4V.
3. Guaranteed by design and characterization, and not tested.
