Tested with an input pulse = 50 ns. This parameter is guaranteed by characterization for input pulse
widths
Coarse Delay = 0, Fine Delay and Falling Edge Adjust disabled. Case Temperature = 50˚C.
Coarse Delay is monotonic. Fine Delay is Monotonic. Since the fine delay spans close to 2 LSBs of coarse
delay, the summation of digital codes for coarse and fine delays is not monotonic. Proper binary searching
using both the coarse and fine delays is achieved first with the coarse (with SFD=1), and then with the fine
delays as separate searches.
