Table 1–13. Fast PLL Pins (Part 3 of 3)
PLLs 3, 4, 9, and 10 are not available on Stratix GX devices for general-purpose configuration. These PLLs are part
of the HSSI block. See AN 236: Using Source-Synchronous Signaling with DPA in Stratix GX Devices for more
information.

1–13:
Stratix and Stratix GX devices provide a hierarchical clock structure and
multiple PLLs with advanced features. The large number of clocking
resources in combination with the clock synthesis precision provided by
enhanced and fast PLLs provides a complete clock management solution.
Global & Hierarchical Clocking
Stratix and Stratix GX devices provide 16 dedicated global clock
networks, 16 regional clock networks (4 per device quadrant), and
8 dedicated fast regional clock networks. These clocks are organized into
a hierarchical clock structure that allows for up to 22 clocks per device
region with low skew and delay. This hierarchical clocking scheme
provides up to 48 unique clock domains within Stratix and Stratix GX
devices.
There are 16 dedicated clock pins (CLK[15..0]) on Stratix devices and
12 dedicated clock pins (CLK[11..0]) on Stratix GX devices to drive
either the global or regional clock networks. Four clock pins drive each
side of the Stratix device, as shown in
GX devices, four clock pins drive the top, left, and bottom sides of the
device. The clocks on the right side of the device are not available for
general-purpose PLLs. Enhanced and fast PLL outputs can also drive the
global and regional clock networks.
Analog ground for PLL 9. You can connect this pin to the
board.
Guard ring ground for PLL 9. You can connect this pin to the
board.
Analog power for PLL 10. Connect this pin to 1.5 V, even if the PLL is not
used.
Guard ring power for PLL 10. Connect this pin to 1.5 V, even if the PLL is not
used.
Analog ground for PLL 10. Connect this pin to the GND plane on the board.
Guard ring ground for PLL 10. You can connect this pin to the
board.
