“RSSI” detection monitor mode is radio standard independent, the configurable “RSSI” threshold and measurement duration can be set
by API adi_adrv9001_powerSavingAndMonitorMode_MonitorMode_Rssi_Configure(), a “DETECTED” state will be asserted once the
input signal level is beyond the threshold in “DETECTING” state, then the following “Wake Up” procedure will be started.
“SYNC” detection monitor mode is only for DMR standard, the Rx Datapath should be configured in “ Frequency Deviation” mode to
enable the relative functions of RX Demodulator. The correlator will parallelly detect the SYNC code from the incoming data steam, and
up to 14 different SYNC code detection can be supported simultaneously. Similarly, once a SYNC code is detected, ADRV9001 will start
the wake up procedure.
ADRV9001 has the option to buffer the latest incoming data in Monitor Mode “Detecting" cycle, once a valid incoming signal is detected
and the baseband processor has been waked up by ADRV9001, ADRV9001 can send out the buffered Rx data to baseband processor. This
procedure can make sure the baseband processor won’t miss the valid incoming signal when it’s in the sleep state.
Monitor Mode uses same power down modes with System Power Saving, but additional detection function than System Power Saving,
and they can use the same DGPIO as the power saving trigger interface. Users can use either System Power Saving or Monitor Mode, and
these two modes can also be dynamically switched for different time slots, a System Power Saving or Monitor Mode API command
should be sent during each time switching between System Power Saving.
