7.1 Propagation Delay and Pulse Width Distortion
Figure 27 shows how one calculates pulse width distortion (tPWD) and delay matching (tDM) from the propagation delays of channels A and B. It can be measured by ensuring that both inputs are in phase and disabling the dead time function by shorting the DT Pin to VCC.
