4.9 PLL Power Pins
VccPLL should be connected to Vcc. GndPLL should be connected to ground. The PLL supply has to
be sufficiently powered, to avoid any fluctuations of power supply. A capacitor of at least 47uF should
be connected as close as possible to these pins. It is recommended to keep the lines between 3.3V
power supply and the Vcc pins as short as possible with wide PCB traces for Vcc, VccPLL, Gnd and
GndPLL.
