Recommended Circuit Diagram
Used with a clean low impedance power supply the
TFDU5307 only needs an external series current lim-
iting resistor. However, depending on the entire sys-
tem design and board layout, additional components
may be required (see figure 1).
The capacitor C1 is buffering the supply voltage and
eliminates 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 the current limiting resistor and this
is supply voltage dependent, see derating curve in fig-
ure 4, to avoid too high internal power dissipation.
Vishay’s transceivers integrate a sensitive receiver
and a built-in power driver. The combination of both
needs a careful circuit board layout. The use of thin,
long, resistive and inductive wiring should be avoided.
The inputs (Txd, SD) and the output Rxd should be
directly (DC) coupled to the I/O circuit.
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 voltages and injected noise. An
unstable power supply with dropping voltage during
transmission may reduce the sensitivity (and trans-
mission range) of the transceiver.
The placement of these parts is critical. It is strongly
recommended to position C2 as close as possible to
the transceiver power supply pins. A Tantalum capac-
itor 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 rise time. In that case another
4.7
μ
F (type, see table under C1) at V
CC2
will be help-
ful.
Under extreme EMI conditions as placing an RF-
transmitter antenna on top of the transceiver, we rec-
ommend to protect all inputs by a low-pass filter, as a
minimum a 12 pF capacitor, especially at the Rxd
port.
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" Paul Horow-
itz, Winfield Hill, 1989, Cambridge University Press,
ISBN: 0521370957.
