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 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.
