The Cyclone III device family provides up to 16 dedicated clock pins (CLK[15..0])
that can drive the global clocks (GCLKs). The Cyclone III device family supports four
dedicated clock pins on each side of the device except EP3C5 and EP3C10 devices.
EP3C5 and EP3C10 devices only support four dedicated clock pins on the left and
right sides of the device.
For more information about the number of GCLK networks in each device density,
refer to the
GCLKs drive throughout the entire device, feeding all device quadrants. All resources
in the device (I/O elements, logic array blocks (LABs), dedicated multiplier blocks,
and M9K memory blocks) can use GCLKs as clock sources. Use these clock network
resources for control signals, such as clock enables and clears fed by an external pin.
Internal logic can also drive GCLKs for internally generated GCLKs and
asynchronous clears, clock enables, or other control signals with high fan-out.
