Integrated Low Profile Transceiver Module
for Telecom Applications – IrDA Standard
Description
The miniaturized TFDU4201 is an ideal transceiver for
Package
applicationsintelecommunicationslikemobilephones
and pagers. The device is mechanically designed for
lowest profile with a height of only 2.8 mm. The
infrared transceiver is compatible to the IrDA Low
Power physical layer specification version up to a data
rate of 115 kbit/s. For higher output intensities with an
identical package solution the TFDU4202 is designed.

Split power supply: The receiver circuit only is connected to a regulated power supply. The high IRED
current can be supplied by a less controlled power line or directly from the battery. That feature saves
power supply costs. TELEFUNKEN introdused this feature as the world first with the 4000 series
**) Depending on the designs different applications need an optical feedback for test purposes or must be quiet
(e.g. in Windows CE applications).

Application Hints
Shut down
The TFDU4201 does not need any external
component when operated at a “clean“ power supply
as e.g. two NiCd or NiMH rechargeable batteries in
series. In a noisy ambient it is recommended to add a

suppression. RF noise picked up from the ambient on
the supply lines can be easily suppressed by a 100 nF
ceramic capacitor (X7R type is recommended placed
The receiver is in specified conditions after the defined
latency. In a UART related application after that time
(typically 50 µs) the receiver buffer of the UART must
be cleared. Therefore the transceiver has to wait at
least the specified latency after receiving the last bit
before starting the transmission to be sure that the
corresponding receiver is in a defined state.

suppressed by an RC combination as shown in the
schematics. R1 can vary from 0 to 5 The C1
range is up to 4.7 F. During transmisssion V should

not drop below the min. power supply voltage. A
combination of a tantalum with a ceramics capacitor
will be still more efficient in very noisy conditions
However, one should keep in mind a low impedance
wiring is more cost efficient than adding larger
capacitors.

Ozone Depleting Substances Policy Statement
It is the policy of Vishay Semiconductor GmbH to
1. Meet all present and future national and international statutory requirements.
2. Regularly and continuously improve the performance of our products, processes, distribution and operating
systems with respect to their impact on the health and safety of our employees and the public, as well as
their impact on the environment.
It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as
ozone depleting substances (ODSs).
The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs and
forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban
on these substances.
Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of
ODSs listed in the following documents.
1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively
2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental
Protection Agency (EPA) in the USA
3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively.
Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting
substances and do not contain such substances.
We reserve the right to make changes to improve technical design and may do so without further notice.
Parameters can vary in different applications. All operating parameters must be validated for each customer application
by the customer. Should the buyer use Vishay Telefunken products for any unintended or unauthorized application, the
buyer shall indemnify Vishay Telefunken against all claims, costs, damages, and expenses, arising out of, directly or
indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
