TCP = Crossing Point
Tra, Trb, Tfa, and Tfb are propagation delay
measurements to the 20% and 80% levels.
FIGURE 8. Propagation Delay Timing for Calculation of Driver Differential Propagation Delays
Note 12: The input pulse is supplied by a generator having the following characteristics:
<

Note 13: C
includes probe and stray capacitance.
L
Note 14: Diodes are 1N916 or equivalent.
Note 15: Differential propagation delays are calculated from single-ended propagation delays measured from driver input to the 20% and 80% levels on the driver
outputs (See Figure 8).
