In this mode the MUXOUT pin will be high when the VCO calibration has finished, the lock detect delay timer is finished running, and the PLL is locked. This indicator may remain in its current state (high or low) if the OSCin signal is lost. The true status of the indicator will be updated and resume its operation only when a valid input reference to the OSCin pin is returned. An alternative method to monitor the OSCin of the PLL is recommended. This indicator is reliable as long as the reference to OSCin is present.
The output of the device can be automatically muted when lock detect indicator “Vtune and VCOCal” is low. This feature is enabled with the field OUT_MUTE (register R0[9]) asserted.
