PLLs 1 to 4 and 7 to 10 are fast PLLs. PLLs 5, 6, 11, and 12 are enhanced PLLs.
CLK4, CLK6, CLK12, and CLK14 feed the corresponding PLL’s inclk0 port.
CLK5, CLK7, CLK13, and CLK15 feed the corresponding PLL’s inclk1 port.
The EP1S40 device in the 780-pin FineLine BGA package does not support PLLs 11 and 12.
