The data signal output
The terminal is pulled up with a resistor.
The output signal level is 0 to Vcc.
The AF signal output terminal
The signal output level is -10.5dBm typ.
(Fm=1 kHz /Fmod=+/-3 kHz, 100 k ohm)
The receiving level output
The level indicates the strength of RF level.
Note that the output voltage may be reduced
depending on the load impedance to be
connected.
The power on/off control terminal (Low active).
A voltage of VCC-1.8 V or lower voltage makes
the circuit active and VCC-0.6 V or higher
disables the circuit.
Please control this terminal with an open-
I
collector or open-drain output.
Note that leakage current will flow if there is a
potential difference between VCC and the
CTRL.
Do not apply a voltage of VCC+0.3 V or higher
to the CTRL pin.
The power supply terminal.
-
Operates on 3.0 to 14 V.
The ground.
-
Connect to the ground of the control board.
The antenna terminal Connect an antenna with
50 ohm impedance.
-
The ground terminal for the antenna.
Solder jumpers for frequency channel setting.
This terminal is pulled-up to the internal power
supply.
