Chapter 5: Clock Networks and PLLs in the Cyclone III Device Family
Clock Networks

The inputs to the five clock control blocks on each side must be chosen from among
the following clock sources:
■
■
■
■
From the clock sources listed above, only two clock input pins, two PLL clock
outputs, one DPCLK or CDPCLK pin, and one source from internal logic can drive into
any given clock control block, as shown in
Out of these five inputs to any clock control block, the two clock input pins and two
PLL outputs are dynamically selected to feed a GCLK. The clock control block
supports static selection of the signal from internal logic.

Figure 5–3. Clock Control Blocks on Each Side of the Cyclone III Device Family
Note to
(1) The left and right sides of the device have two DPCLK pins; the top and bottom of the device have four DPCLK pins.
You can disable the Cyclone III device family GCLK (power down) by using both
static and dynamic approaches. In the static approach, configuration bits are set in the
configuration file generated by the Quartus II software, which automatically disables
unused GCLKs. The dynamic clock enable or disable feature allows internal logic to
control clock enable or disable of the GCLKs in the Cyclone III device family.
When a clock network is disabled, all the logic fed by the clock network is in an
off-state, thereby reducing the overall power consumption of the device. This function
is independent of the PLL and is applied directly on the clock network, as shown in
Figure 5–1 on page
You can set the input clock sources and the clkena signals for the GCLK
multiplexers through the Quartus II software using the ALTCLKCTRL megafunction.
