rameter will have no effect and the PLL output will continue until CLK_IN is re-applied (see Figure 8).

Once CLK_IN is re-applied, the PLL will go unlocked only for the time it takes to acquire lock; the

PLL_OUT state will be determined by the ClkOutUnl parameter during this time.

PLL_OUT continues while the PLL re-acquires lock (see Figure 9). When ClkSkipEn is disabled and

CLK_IN is removed the PLL output will continue until CLK_IN is re-applied at which point the PLL will go

unlocked only for the time it takes to acquire lock; the PLL_OUT state will be determined by the ClkOutUnl

parameter during this time. When ClkSkipEn is enabled and CLK_IN is removed the PLL output clock will
