Serial Infrared Transceiver SIR, 115.2 kbit/s,
2.7 V to 5.5 V Operation
Description
The TFDU4100 is an infrared transceiver module
compliant with the IrDA standard for serial infrared
(SIR) data communication, supporting IrDA speeds
up to 115.2 kbit/s. The transceiver module consists of
a PIN photodiode, an infrared emitter (IRED), and a
low-power analog control IC to provide a total front-
end solution in a single package. This SIR transceiver
is using the small BabyFace package. The transceiv-
ers are capable of directly interfacing with a wide vari-
ety of I/O chips which perform the pulse-width
modulation/demodulation function, including Vishay
Semiconductors’ TOIM4232. At a minimum, a cur-
18102
rent-limiting resistor in series with the infrared emitter
and a V_CC bypass capacitor are the only external
components required to implement a complete solu-
tion.
