Cyclone III device PLLs provide you with complete control of device
clocks and system timing. The ability to reconfigure the PLL counter clock
frequency and phase shift in real time can be especially useful in
prototyping environments, allowing you to sweep PLL output
frequencies and adjust the output clock phase shift dynamically. These
PLLs are capable of offering flexible system-level clock management that
