4.8.1
In the PLLVcc and PLLVss connection pattern for the PLL, signal lines from the board power
supply pins must be as short as possible and pattern width must be as wide as possible to reduce
inductive interference.
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 pin Vcc and digital power supply pin PVcc should not
supply the same resources on the board if at all possible.
