Low propagation delay is an important factor in high-speed circuit design on newer processors that level shift at low inputs or outputs. Inconsistent or higher propagation delay in an IC can cause data errors at a system level.
Table 3-1 compares TXV and competitor, with TXV measuring overall lower or faster propagation delay than competitor (15 pF / 125 MHz / 25°C, typical bench data).
