to ensure that pathological signals can be coupled without a significant DC component
occurring. Please see Application Information on page 13 for more details.

The output protection diodes act as a varactor (voltage controlled capacitor) as shown in
Figure 5-3. Therefore, when measuring return loss at the GS1578A output, it is necessary
to take the measurement for both a logic high and a logic low output condition.
