1.
The PLL dynamic contribution depends on the input clock frequency, the number of output clock signals generated
by the PLL, and the frequency of each output clock. If a PLL is used to generate more than one output clock, include
each output clock in the formula by adding its corresponding contribution (P
contribution.
