Table 6–12. PLL Input Signals (Part 1 of 2)
You can feed the inclk0 or inclk1 clock input from any one of four dedicated clock pins located on the same side
of the device as the PLL.
You can drive to global or regional clock networks or dedicated external clock output pins. n = 6 for Left/Right PLLs
and n = 9 for Top/Bottom PLLs.
