PLL Power Supply Filter Circuit
7.5 PLL Power Supply Filter Circuit
To ensure PLL stability, the power supply to the PLL power pin should be filtered using a
circuit similar to the one in Figure 7-5. The circuit should be placed as close as possible to
the PLL power pin to ensure maximum noise filtering.
