1.8 External Feedback Inputs
In addition to the static delay compensation described in the “External Feedback Inputs” section on page 20, the
ZL30121 also provides the option of dynamic delay compensation to minimize path delay variation associated with
external clock drivers and long PCB traces. This is accomplished by re-directing the internal DPLL1 feedback path
to external pins and closing the loop externally as shown in Figure 9.
