added
Since the analog power supply pins of the PLL are
sensitive to the noise, the system may malfunction due to
inductive interference at the other power supply pins. To
prevent such malfunction, the analog power supply pins
and the digital power supply pins Vcc and PVcc should not
supply the same resources on the board if at all possible.
sensitive to the noise, the system may malfunction due to
inductive interference at the other power supply pins. To
prevent such malfunction, the analog power supply pins
and the digital power supply pins Vcc and PVcc should not
supply the same resources on the board if at all possible.
Ensure that PLLVcc has the same electric potential as Vcc.
