Pin Description:
RF GND
(pin 1)
RF ground pin, internally connected to pin 4 (0V).
This pin should ideally be connected to the
nearest ground plane (e.g. coax braid, main PCB
ground plane etc.)
RF OUT
(pin2)
50
RF antenna output. To achieve best results
the antenna impedance must match that of the
module.
V
CC
(pin 3)
+Ve supply pin (3.0 to 9.0 volts). The module will
generate RF when V
CC
is present. It is strongly
recommended that a 100nF capacitor decouples
the supply rail as close as possible to this pin.
GND
(pin 4)
Supply and data ground connection, connected to
pin 1.
Data IN
(pin 5)
This input has an impedance of 47K
and should
ideally be driven by a CMOS logic drive or
compatible. The drive circuitry should be supplied
with the same supply voltage as the Tx module.

Figure 2: Receiver
RF IN (pin 1)
50 RF input from antenna, connect using
shortest possible route. This input is isolated from
the internal circuit using the air gap of the front
end SAW RF filter
RF GND (pin 2)
RF ground connection, preferable connected to a
solid plane.
RSSI (pin 3)
The Received Signal Strength Indicator provides a
DC output voltage proportional to the FR input
signal. The amplitude of the RSSI voltage
increases with increasing RF signal strength.
GND (pin 4)
Connect to power supply ground.
V
CC
(pin 5)
+Ve supply pin. Operation from a 5V supply able
to source6mA at less than V
p-p
ripple.
AF (pin 6)
Audio frequency output.
DATA OUT (pin 7)
CMOS compatible output. This may be used to
drive external decoders.
Part No
