Recommended Circuit Diagram
The TFBS4710 integrates a sensitive receiver and a
built-in power driver. This combination needs a care-
ful circuit 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 combination of resistor R1 and capacitors C1,
C2, C3 and C4 filter out any power supply noise to
provide a smooth supply voltage.
The placement of these components is critical. It is
strongly recommended to position C3 and C4 as
close as possible to the transceiver power supply
pins. A Tantalum capacitor should be used for C1 and
C3 while a ceramic capacitor should be used for C2
and C4.
A current limiting resistor is not needed for normal
operation. It is strongly recommended to use the Rled
values mentioned in Table 1 below for high tempera-
ture operation. For Low Power Mode, IRED Anode
voltage of less than 5 V is recommended.
Under extreme EMI conditions as placing a RF -
transmitter antenna on top of the transceiver, it is rec-
ommended to protect all inputs by a low-pass filter, as
a minimum a 12 pF capacitor, especially at the RXD
port.
Basic RF design rules for circuit design should be fol-
lowed. Especially longer signal lines should not be
used without proper termination. For reference see

I/O and Software
In the description, already different I/Os are men-
tioned. Different combinations are tested and the
function verified with the special drivers available
from the I/O suppliers. In special cases refer to the I/
O manual, the Vishay application notes, or contact
directly Vishay Sales, Marketing or Application.
