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. TEMIC’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 TEMIC’s

TOIM3000 and 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.
