GND 3 4 5 DETECT 0 VOLT Vcc 6 AF 7 DATA Connects to the Receiver antenna.
Has nominal 50Ω impedance and is capacitively isolated from internal circuit.
Should be connected to any ground plane against which the antenna works.
(Internally connected to pin 4).
May be used to derive a carrier detect to enable external circuit when a signal is being received.
If the detect function is unused connect a 10k Ω resistor to Vcc (pin 5).
Ground for Supply.
