Internal regulated supply (2.7 V to 3.4 V) for analog circuitry
External supply input to chip (2.7 V to 5.5 V)
Internal regulated supply (2.7 V to 5 V); normally connected to VDD_PA (pin 4)
INP Supply for PA; normally connected externally to VDD_RF (pin 3)
RF output (selectable output power: 100 mW or 200 mW, with V
Negative supply for PA; normally connected to circuit ground
Negative supply for receive inputs; normally connected to circuit ground
INP Main receive input
INP Auxiliary receive input
Chip substrate ground
Bandgap voltage (V
BG
Selection between ASK and OOK modulation (0 = ASK, 1 = OOK) for direct mode 0 and 1.
BID
It can be configured as an output to provide the received analog signal output.
Interrupt request
INP External data modulation input for direct mode 0 or 1
Subcarrier digital data output (see register 0x1A and 0x1B definitions)
Negative supply for internal analog circuits. Connected to GND.
INP Supply for I/O communications (1.8 V to VIN) level shifter. VIN should be never exceeded.
