PLL Modes of Operation
PLLs have many uses within a logic design. The two most popular are Clock Injection Removal and Clock Phase
Adjustment. These two modes of operation are described below.
PLL Clock Injection Removal
In this mode the PLL is used to reduce clock injection delay. Clock injection delay is the delay from the input pin of
the device to a destination element such as a flip-flop. The phase detector of the PLL aligns the CLKI with CLKFB.
If the CLKFB signal comes from the clock tree (CLKOP), then the PLL delay and the clock tree delay is removed.
Figure 9-10 Illustrates an example block diagram and waveform.
