Fast Infrared Transceiver Module (MIR, 1.152 Mbit/s)
for 2.7 V to 5.5 V Operation
Description
The TFDU5103 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 1.152 Mbit/s (MIR), and
carrier based remote control modes up to 2 MHz. The
transceiver module consists of a PIN photodiode, an
infrared emitter (IRED), and a low-power CMOS con-
trol IC to provide a total front-end solution in a single
package.

Vishay MIR transceivers are available in different
package options, including this BabyFace package
(TFDU5103). 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 PC87338, PC87108 and
PC87109, SMC’s FDC37C669, FDC37N769 and
CAM35C44, and Hitachi’s SH3. At a minimum, a VCC
bypass capacitor is the only external component
required implementing a complete solution.
TFDU5103 has a tri-state output and is floating in
shutdown mode with a weak pull-up.
Features

1) Receive mode only.
In transmit mode, add additional 85 mA (typ) for IRED current. Add Rxd output current depending on Rxd load.
2) Standard Illuminant A
3) The typical threshold level is between 0.5 x VCC/2 (VCC = 3 V) and 0.4 x VCC (VCC = 5.5 V) . It is recommended to use the specified
min/ max values to avoid increased operating current.

Current Derating Diagram
Figure 5 shows the maximum operating temperature
when the device is operated without external current
limiting resistor. A power dissipating resistor of 2 Ω is
recommended from the cathode of the IRED to
Ground for supply voltages above 4 V. In that case
the device can be operated up to 85 °C, too.
