PIN DESCRIPTION
CDP-TX-02E-R
Pin name I/O Description Equivalent circuit
ANT O
RF output 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.
DATAIN I
Digital data input terminal
Interface voltage: H = 3 to 5.5V L = GND
