Fast Infrared Transceiver Module Family
(FIR, 4 Mbit/s) for 2.6 V to 5.5 V Operation
Description
The
TFDU6101E,
TFDT6501E are a family of low–power infrared
transceiver modules compliant to the IrDA standard for
fast infrared data communication, supporting IrDA
speeds up to 4.0 Mbit/s (FIR), HP-SIR, Sharp ASK
and carrier based remote control modes up to 2 MHz.
Integrated within the transceiver modules are a photo
PIN diode, an infrared emitter (IRED), and a
low–power CMOS control IC to provide a total
front–end solution in a single package.
Vishay Telefunken’s FIR transceivers are available in
four package options, including our Baby Face
package (TFDU610xE), the standard setting, once
TFDS6401,
TFDS6501E,
smallest FIR 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 devices which perform the modulation/
demodulation
function,
Semiconductor’s PC87338, PC87108 and PC87109,
SMC’s FDC37C669, FDC37N769 and CAM35C44,
and Hitachi’s SH3. At a minimum, a current–limiting
resistor in series with the infrared emitter and a
V
CC
bypass capacitor are the only external
components required implementing a complete
solution.
