Vishay Telefunken
2.7 V to 5.5 V Serial Infrared Transceiver
Module Family (SIR, 115.2 kbit/s)
Description
The TFDU4100, TFDS4500, and TFDT4500 are a
family of low–power infrared transceiver modules
compliant to the IrDA 1.2 standard for serial infrared
(SIR) data communication, supporting IrDA speeds up
to 115.2 kbit/s. Integrated within the transceiver
modules are a photo PIN diode, infrared emitter
(IRED), and a low–power analog control IC to provide
a total front–end solution in a single package.
Telefunken’s SIR transceivers are available in three
package options, including our BabyFace package
(TFDU4100), the smallest SIR transceiver available
on the market. This wide selection provides flexibility
for a variety of applications and space constraints. The
transceivers are capable of directly interfacing with a
wide variety of I/O chips which perform the
pulse–width modulation/demodulation function,
including Telefunken’s TOIM3000/ TOIM3232. At a
minimum, a current– limiting resistor in series with the
infrared emitter and a VCC bypass capacitor are the
only external components required to implement a
complete solution.

* Note:
Transmitted data: continuously transmitted “0”. In normal data transfer operation “0” and “1” will be transmitted with
the same probability. Therefore, for that case, about a factor of two of safety margin is included. However, for worst
case thermal stress testing such data pattern are often used and for this case the 400 mW/sr value has to be taken.
