Table 2–17. Arria GX Device PLL Availability
The global or regional clocks in a fast PLL's transceiver block can drive the fast PLL input. A pin or other PLL must
drive the global or regional source. The source cannot be driven by internally generated logic before driving the fast
PLL.
EP1AGX20C, EP1AGX35C/D, EP1AGX50C and EP1AGX60C/D devices only have two fast PLLs (PLLs 1 and 2), but
the connectivity from these two PLLs to the global and regional clock networks remains the same as shown in this
table.
PLLs 3, 4, 9, and 10 are not available in Arria GX devices.
4 or 8 PLLs are available depending on C or D device and the package option.
4or 8 PLLs are available depending on C, D, or E device option.
