CDP-RX-02E-R
Pin name I/O Description Equivalent circuit
ANT O
RF input terminal
Antenna impedance nominal 50 Ω
GND I
The ground for the power supply.
Connect it to the ground plane as
well as to the bottom part of the case.
The ground plane has an impact on
the range and the stability of
operation.
VCC I
The power supply terminal. The
supply voltage is DC 3.0 to 12 V.
Power supply noise and ripple have
an impact on performance, so
eliminate them as far as possible with
filters and capacitors.
RSSI O
The receive level output of the
receiver.
The strength of the RF level (electric
field intensity) is output as a direct-
current voltage.
DATA I
Digital data output terminal
Interface voltage: H = Vcc L = GND
AF O
The demodulated output of the
receiver. The DC offset is about 1 V.
Refer to the specifications for the
amplitude level.
