VISHAY
Fast Infrared Transceiver Module (FIR, 4 Mbit/s)
for 2.7 V to 5.5 V Operation
Description
The TFDU6102 is a low-power infrared transceiver
module compliant to the latest IrDA physical layer
standard for fast infrared data communication, sup-
porting IrDA speeds up to 4.0 Mbit/s (FIR), and carrier
based remote control modes up to 2 MHz. Integrated
within the transceiver module are a PIN photodiode,
an infrared emitter (IRED), and a low-power CMOS
control IC to provide a total front-end solution in a sin-
gle package.
Vishay FIR transceivers are available in different
package options, including this BabyFace package
(TFDU6102). 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 devices which perform the
modulation/
National Semiconductor’s PC87338, PC87108 and
PC87109, SMC’s FDC37C669, FDC37N769 and
CAM35C44, and Hitachi’s SH3. TFDU6102 has a tri-
state output and is floating in shut-down mode with a
weak pull-up.

The combi- nation of both needs a careful circuit board layout. The use of thin, long, resistive and inductive wiring should be avoided. The inputs (Txd, SD, Mode) and the output Rxd should be directly (DC) coupled to the I/O circuit ...
