When measuring return loss at the GS1528 output, it is necessary to take the
measurement for both a logic high and a logic low output condition. This is because the
output protection diodes act as varactors (voltage controlled capacitors) as shown in
Figure 3-3.
Consequently, the output capacitance of the GS1528 is dependent on the logic state of
the output.
