Clock Division
To obtain a lower frequency clock from a higher frequency clock, use a PLL to divide
the clock. PLL has a predictable output delay, and you can also change the phase of
the output signal to compensate for any delay. Using cascaded registers to divide the
clock introduces delay to the clock. As the ripple carry register chain propagates the
delay through the chain, there will be phase shift between the input clock and the
output clocks, and between different output clocks that are generated. Also, the delay
depends on the placement of the registers.
Inverted Clock
Use a PLL to generate an inverted clock, instead of using a NOT gate implemented
with an LE. The PLL allows you to set the phase shift of the output signal and
compensate for any delay between the input and output signals.
Multiplexed Clock
Some user designs require different clock source selection. Use the dedicated clock
control block or the PLL clock switchover feature of the Cyclone III device to
multiplex clock inputs. The clock control block allows up to four different clock source
selections, either from clock pins or PLL outputs as the source for the clock network.
You can dynamically select the clock source from two clock input pins and two PLL
outputs through the altclkctrl megafunction.
The PLL clock switchover feature also allows you to dynamically select between two
clock sources, either from clock input pins or output clocks from another PLL.
For more information about the Cyclone III clock control block and the PLL clock
switchover feature, refer to the
in volume 1 of the Cyclone III Device Handbook.

Gated Clock
Gated clock allows users to turn off the clock signal. However, the recommended way
to turn off the clock in the Cyclone III device is to use the clock control block. The
clock control block allows you to power down the clock network. Use the altclkctrl
megafunction to instantiate the clock control block.
For more information about the Cyclone III clock control block, refer to the
Networks and PLLs in Cyclone III Devices
Handbook.
