Vishay Semiconductors
Recommended Circuit Diagram
Vishay Semiconductors transceivers integrate a sen-
sitive receiver and a built-in power driver. The combi-
nation of both needs a careful circuit board layout.
The use of thin, long, resistive and inductive wiring
should be avoided. The inputs (Txd, SD, Mode) and
the output Rxd should be directly (DC) coupled to the
I/O circuit.
The capacitor C1 is buffering the supply voltage and
reduces the influence of the inductance of the power
supply line. This one should be a Tantalum or other
fast capacitor to guarantee the fast rise time of the
IRED current. The resistor R1 is only necessary for
higher operating voltages and elevated temperatures,
see derating curve in figure 7, to avoid too high inter-
nal power dissipation.
The capacitor C2 combined with the resistor R2 is the
low pass filter for smoothing the supply voltage. R2,
C1 and C2 are optional and dependent on the quality
of the supply voltage V
CCx
and injected noise. An
unstable power supply with dropping voltage during
transmission may reduce sensitivity (and transmis-
sion range) of the transceiver.
The placement of these parts is critical. It is strongly
recommended to position C2 as near as possible to
the transceiver power supply pins. An Tantalum
capacitor should be used for C1 while a ceramic
capacitor is used for C2.
In addition, when connecting the described circuit to
the power supply, low impedance wiring should be
used.
When extended wiring is used the inductance of the
power supply can cause dynamically a voltage drop
at V
CC2
. Often some power supplies are not apply to
follow the fast current is rise time. In that case another
4.7
μ
F (type, see table under C1) at V
CC2
will be help-
ful.
Keep in mind that basic RF-design rules for circuit
design should be taken into account. Especially
longer signal lines should not be used without termi-
nation. See e.g. "The Art of Electronics" by Paul
Horowitz and Winfield Hill, 1989, Cambridge Univer-
sity Press, ISBN: 0521370957.
