Fast Infrared Transceiver Module (FIR, 4 Mbit/s)
for 2.4 V to 5.5 V Operation
TFDU6103
Vishay Semiconductors
DESCRIPTION
The TFDU6103 is a low-power infrared transceiver module
compliant to the latest IrDA
physical layer standard for fast
infrared data communication, supporting IrDA speeds up to
4 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
single package.
Vishay FIR transceivers are available in different package
options, including this BabyFace package (TFDU6103). 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/demodulation function, including
National
Semiconductor’s
PC87109,
SMC’s
FDC37C669,
CAM35C44, and Hitachi’s SH3. TFDU6103 has a tri-state
output and is floating in shut-down mode with a weak pull-up.
