Stratix II Device Handbook, Volume 1
EP2S15 and EP2S30 devices only have two enhanced PLLs (5 and 6), but the connectivity from these two PLLs to
the global and regional clock networks remains the same as shown.
If the design uses the feedback input, you lose one (or two, if FBIN is differential) external clock output pin.
The enhanced PLLs can also be driven through the global or regional clock netowrks. 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.
