DESCRIPTION
The TFBS4711 is a low profile, infrared data transceiver
module. It supports IrDA® data rates up to 115.2 kbit/s (SIR).
The transceiver module consists of a PIN photodiode, an
infrared emitter (IRED), and a low-power CMOS control IC to
provide a total front-end solution in a single package.
The device is designed for the low power IrDA standard with
an extended range on-axis up to 1 m. The RXD output pulse
width is independent of the optical input pulse width and
stays always at a fixed pulse width thus making the device
optimum for standard endecs. TFBS4711 has a tri-state
output and is floating in shut-down mode with a weak pull-up.
The shut down (SD) feature cuts current consumption to
typically 10 nA.

In the Vishay transceiver datasheets the following
nomenclature is used for defining the IrDA operating modes:
SIR: 2.4 kbit/s to 115.2 kbit/s, equivalent to the basic serial
infrared standard with the physical layer version IrPhy 1.0
MIR: 576 kbit/s to 1152 kbit/s
FIR: 4 Mbit/s
VFIR: 16 Mbit/s
MIR and FIR were implemented with IrPhy 1.1, followed by
IrPhy 1.2, adding the SIR low power standard.

Notes
(1) T

Typical values are for design aid only, not guaranteed nor subject to production testing.
(2) Equivalent to IrDA background light and electromagnetic field test: fluorescent lighting immunity.
(3) IrDA sensitivity definition: minimum irradiance E in angular range, power per unit area. The receiver must meet the BER specification while
e
the source is operating at the minimum intensity in angular range into the minimum half-angular range at the maximum link length.
(4) Maximum irradiance E in angular range, power per unit area. The optical delivered to the detector by a source operating at the maximum
e
intensity in angular range at minimum link length must not cause receiver overdrive distortion and possible ralated link errors. If placed at the
active output interface reference plane of the transmitter, the receiver must meet its bit error ratio (BER). For more definitions see the
document “Symbols and Terminology” on the Vishay website.
(5) Using an external current limiting resistor is allowed and recommended to reduce IRED intensity and operating current when current reduction
is intended to operate at the IrDA low power conditions. E.g. for VCC2 = 3.3 V a current limiting resistor of RS = 56  will allow a power
minimized operation at IrDA low power conditions.
(6) Due to this wavelength restriction compared to the IrDA spec of 850 nm to 900 nm the transmitter is able to operate as source for the standard
remote control applications with codes as e.g. Phillips RC5/RC6® or RECS 80.

*) R1 is optional when reduced intensity is used
CRCW-1206-47R0-F-RT1
The inputs (TXD, SD) and the output RXD should be directly
connected (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 VCC1
and injected noise. An unstable power supply with dropping
voltage during transmision may reduce the sensitivity (and
transmission 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 pins.
When extended wiring is used as in bench tests the
inductance of the power supply can cause dynamically a
voltage drop at VCC2. Often some power supplies are not
able to follow the fast current rise time. In that case another
4.7 µF (type, see table under C1) at VCC2 will be helpful.
Under extreme EMI conditions as placing an
RF-transmitter antenna on top of the transceiver, we
recommend to protect all inputs by a low-pass filter, as a
minimum a 12 pF capacitor, especially at the RXD port. The
transceiver itself withstands EMI at GSM frequencies above
500 V/m. When interference is observed, the wiring to the
inputs picks it up. It is verified by DPI measurements that as
long as the interfering RF - voltage is below the logic
threshold levels of the inputs and equivalent levels at the
outputs no interferences are expected.
One should keep in mind that basic RF - design rules for
circuits design should be taken into account. Especially
longer signal lines should not be used without termination.
See e.g. “The Art of Electronics” Paul Horowitz, Winfield Hill,
1989, Cambridge University Press, ISBN: 0521370957.
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, which may be used to reduce the
operating current to levels below the specified controlled
values for saving battery power.
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 shutdown input
must be grounded for normal operation, also when the
shutdown function is not used.

In the description, already different I/Os are mentioned.
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

For operating at RS232 ports the ENDECS TOIM4232 or

Figure 4 shows an example of a typical application for to
work with a separate supply voltage VS and using the
transceiver with the IRED anode connected to the
unregulated battery Vbatt. This method reduces the peak load
of the regulated power supply and saves therefore costs.
Alternatively all supplies can also be tied to only one voltage
source. R1 and C1 are not used in this case and are
depending on the circuit design in most cases not necessary.
