Infrared Transceiver Module (SIR, 115.2 kbit/s)
for IrDA® Applications
FEATURES
• Compliant to the latest IrDA physical layer
specification (9.6 kbit/s to 115.2 kbit/s) and TV
remote control, bi-directional operation included
• Operates from 2.4 V to 5.5 V within specification
over full temperature range from - 30 °C to
+ 85 °C
• Split power supply, transmitter and receiver can
be operated from two power supplies with
relaxed requirements saving costs, US patent

DESCRIPTION
The TFDU4301 is a low profile (2.5 mm) infrared transceiver
module. It is compliant to the latest IrDA® physical layer
standard for fast infrared data communication, supporting
IrDA speeds up to 115.2 kbit/s (SIR) and carrier based
remote control. The transceiver module consists of a PIN
photodiode, an infrared emitter (IRED), and a low-power
control IC to provide a total front-end solution in a single
package.
This device covers an extended IrDA low power range of
close to 1 m. With an external current control resistor the
current can be adjusted for shorter ranges.
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. TFDU4301
has a tri-state output and is floating in shut-down mode with
a weak pull-up.
• Extended IrDA low power range to about 70 cm
• Typical remote control range 12 m
• Low power consumption (< typ. supply current 70 µA)
• Power shutdown mode (< 1 µA shutdown current in full
temperature range, up to 85 °C)
• Low profile (2.5 mm) (L x W x H in mm): 8.5 × 2.5 × 3.1
• Surface mount package
• High efficiency emitter
• Low profile (universal) package capable of surface mount
soldering to side and top view orientation
• Directly interfaces with various super I/O and controller
devices as e.g. TOIM4232 or TOIM5232
• Tri-state-receiver output, floating in shut down with a weak
pull-up
APPLICATIONS
• Compliant with IrDA background light specification
• EMI immunity in GSM bands > 300 V/m verified
• Qualified for lead (Pb)-free and Sn/Pb processing (MSL4)
• Ideal for battery operated applications
• Telecommunication products (cellular phones, pagers)
• Digital still and video cameras
• Printers, fax machines, photocopiers, screen projectors
• Medical and industrial data collection
• Diagnostic systems
• Compliant to RoHS directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
• Notebook computers, desktop PCs, palmtop computers
(Win CE, Palm PC), PDAs
• Internet TV boxes, video conferencing systems
• External infrared adapters (dongles)
• Data loggers
• GPS
• Kiosks, POS, point and pay devices including

DESCRIPTION
I/O

Connect IRED anode directly to the power supply (VCC2). IRED current can be
decreased by adding a resistor in series between the power supply and IRED

This Schmitt-Trigger input is used to transmit serial data when SD is low. An

longer than 100 µs. The input threshold voltage adapts to and follows the logic
voltage swing defined by the applied supply voltage.

Definitions:
PINOUT
In the Vishay transceiver data sheets 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
TFDU4301
weight 75 mg
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. IrPhy 1.3
extended the low power option to MIR and FIR and VFIR was
added with IrPhy 1.4. A new version of the standard in any
case obsoletes the former version.

With introducing the updated versions the old versions are
obsolete. Therefore the only valid IrDA standard is the actual
version IrPhy 1.4 (in Oct. 2002).

IrDA sensitivity definition: minimum irradiance Ee in angular range, power per unit area. The receiver must meet the BER specification while
the source is operating at the minimum intensity in angular range into the minimum half-angular range at the maximum link length.
Maximum irradiance Ee in angular range, power per unit area. The optical delivered to the detector by a source operating at the maximum
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.
(4)
(5)
(6)
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 Ω will allow a power
minimized operation at IrDA low power conditions.
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.

The inputs (TXD, SD) and the output RXD should be directly

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
Fig. 1 - Recommended Application Circuit
Note
*) R1 is optional when reduced intensity is used
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.

The TFDU4301 is a lead (Pb)-free transceiver and qualified
for lead (Pb)-free processing. For lead (Pb)-free solder paste
like Sn(3.0-4.0)Ag(0.5-0.9)Cu, there are two standard reflow
profiles: Ramp-Soak-Spike (RSS) and Ramp-To-Spike
(RTS). The Ramp-Soak-Spike profile was developed
primarily for reflow ovens heated by infrared radiation. With
widespread use of forced convection reflow ovens the
Ramp-To-Spike profile is used increasingly. Shown below in
figure 5 and 6 are VISHAY's recommended profiles for use
with the TFDU4301 transceivers. For more details please
refer to the application note “SMD Assembly Instructions”.
A ramp-up rate less than 0.9 °C/s is not recommended.
Ramp-up rates faster than 1.3 °C/s could damage an optical
part because the thermal conductivity is less than compared
to a standard IC.

Wave Soldering
For TFDUxxxx and TFBSxxxx transceiver devices wave
soldering is not recommended.
Manual Soldering
Manual soldering is the standard method for lab use.
However, for
a
production process it cannot be
recommended because the risk of damage is highly
dependent on the experience of the operator. Nevertheless,
we added a chapter to the above mentioned application note,
describing manual soldering and desoldering.
Storage
The storage and drying processes for all VISHAY
transceivers (TFDUxxxx and TFBSxxx) are equivalent to
MSL4.
The data for the drying procedure is given on labels on the
packing and also in the application note “Taping, Labeling,
Storage and Packing”.
