Input Pin
PLLs 5, 6, 11, and 12 are not fast PLLs.
Clock pins CLK0, CLK2, CLK9, CLK11, and pins FPLL[7..10]CLK do not support differential on-chip
termination.
Either a FPLLCLK pin or a CLK pin can drive the corner fast PLLs (PLL7, PLL8, PLL9, and PLL10) when used for
general purpose. CLK pins cannot drive these fast PLLs in high-speed differential I/O mode.
