Document Table of Contents Stripline Layout Propagation Delay

Use the following equation to calculate the stripline trace layout propagation delay.

Figure 78 shows the propagation delay versus the dielectric constant for microstrip and stripline traces. As the εr increases, the propagation delay (tPD) also increases.
