• Manufacturer Part Number: rx2g-433-64-5v
• Description: Uhf Fm Data Transmitter And Receiver Modules
• Manufacturer: Radiometrix Ltd

RX2G receiver
En (Regulator version)
Rx enable. <0.15V shuts down module (current <1uA). >1.7V enables the receiver. Impedance
~1Mohm. Observe slew rate requirements (see apps notes).
RSSI
Received signal strength indicator with 60dB range. See page 4 for typical characteristics.
0V
DC supply ground. Internally connected to pin 2 & 3 and module screen.
Vcc
5V regulated DC supply. Max ripple content 0.1V
AF out
Buffered and filtered analogue output from the FM demodulator. Standing DC bias 2V approx.
External load should be >10kΩ // <100pF.
RXD
This digital output from the internal data slicer is a squared version of the signal on pin 8 (AF).
It may be used to drive external decoders. The data is true data, i.e. as fed to the transmitter.
