Description
RSSI Output
Output RSSI (= Received Signal Strength
Indication) voltage. Connect ground via a
capacitor. This IC has another RSSI signal
for digital processing.
At no use, connect ground via a capacitor.
Antenna Switch Control for RX (In SPI
Mode)
At no use, open this pin.
Address Setting (In EEPROM Mode)
Set a start address to read memory data.
Notice:
Do not supply higher voltage than the level
of COM_VDD. (For example, in the case
of too low / no power supply.) That causes
overcurrent at this pin, as the ESD
protection elements insertion between the
pin and the voltage source.
RF Decoupling Pin
Connect a decoupling capacitor.
At no use, open this pin.
-
RF Input Pin
Do not connect DC voltage except ground
to RF_IN pin.
At no use, open this pin.
