Clock
Input
The global or regional clock input can be driven by an output from another PLL or any dedicated CLK or FCLK pin.
It cannot be driven by internally-generated global signals.
In high-speed differential I/O support mode, this high-speed PLL clock feeds the SERDES. Stratix and Stratix GX
devices only support one rate of data transfer per fast PLL in high-speed differential I/O support mode.
This signal is a high-speed differential I/O support SERDES control signal.
