Clock
INCLK[3..0]
Each clock source can come from any of the four clock pins that are physically located on the same side of the device
as the PLL.
If the feedback input is used, you will lose one (or two, if FBIN is differential) external clock output pin.
Each enhanced PLL has three differential external clock outputs or six single-ended external clock outputs.
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 control block provided the clock control block is fed by an output from another
PLL or a pin-driven dedicated global or regional clock. An internally generated global signal cannot drive the PLL.

Enhanced PLLs
Stratix II GX devices contain up to four enhanced PLLs with advanced
clock management features. These features include support for external
clock feedback mode, spread-spectrum clocking, and counter cascading.

Fast PLLs
Stratix II GX devices contain up to four fast PLLs with high-speed serial
interfacing ability. The fast PLLs offer high-speed outputs to manage the
high-speed differential I/O interfaces.
