GNDA_PLL1
Analog ground for PLL 1. Your can connect this pin to the GND plane on the board.
VCCA_PLL2
Analog power for PLL 2. You must connect this pin to 1.2 V, even if the PLL is not used.
GNDA_PLL2
Analog ground for PLL 2. You can connect this pin to the GND plane on the board.
VCCA_PLL3
Analog power for PLL 3. You must connect this pin to 1.2 V, even if the PLL is not used.
GNDA_PLL3
Analog ground for PLL 3. You can connect this pin to the GND plane on the board.
VCCA_PLL4
Analog power for PLL 4. You must connect this pin to 1.2 V, even if the PLL is not used.
GNDA_PLL4
Analog ground for PLL 4. You can connect this pin to the GND plane on the board.
