APPLICATION CHARACTERISTICS
5.1 Operating Rise/Fall Times
The measurement of the V
CC
and PS pins’ rise and fall time is carried out by using a pulse pattern generator to
control the pins’ ON/OFF status at high speeds, and the zero-scan mode of a spectrum analyzer to set the
maximum/minimum transition time of the output level of the desired RF frequency. Bearing in mind the dependency
of the DC cut capacitor on the rise time, a DC cut capacitor of about 100 pF is required to get the same value (2
μ
s)
as the data sheet. The measurement results are shown in Table 5-1. In addition, the rising/falling waveform of the
μ
PC8106TB is shown in Figure 5-1 as an illustrative example.
