4.7 ANALOG LOCK DETECT FILTER
When the Fo/LD output is configured in analog lock detect mode an external lock detect circuit is needed in order to provide a
steady LOW signal when the PLL is in the locked state. A typical circuit is shown below. The fold output is active low (open drain)
only when analog lock detect mode is selected.
