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 output clock by adding its corresponding contribution (P
contribution.
