Notes to
(1) The global or regional clock input can be driven by an output from another PLL, a pin-driven dedicated global or regional clock, or through a clock
(2) In high-speed differential I/O support mode, this high-speed PLL clock feeds the serializer/deserializer (SERDES) circuitry. Arria GX devices only
(3) This signal is a differential I/O SERDES control signal.
(4) Arria GX fast PLLs only support manual clock switchover.
