Infrared Transceiver Module (SIR, 115.2 kbit/s)
for IrDA
®
Applications
TFDU4301
Vishay Semiconductors
DESCRIPTION
The TFDU4301 is a low profile (2.5 mm) infrared transceiver
module. It is compliant to the latest IrDA
®
physical layer
standard for fast infrared data communication, supporting
IrDA speeds up to 115.2 kbit/s (SIR) and carrier based
remote control. The transceiver module consists of a PIN
photodiode, an infrared emitter (IRED), and a low-power
control IC to provide a total front-end solution in a single
package.
This device covers an extended IrDA low power range of
close to 1 m. With an external current control resistor the
current can be adjusted for shorter ranges.
The RXD output pulse width is independent of the optical
input pulse width and stays always at a fixed pulse width thus
making the device optimum for standard endecs. TFDU4301
has a tri-state output and is floating in shut-down mode with
a weak pull-up.

Definitions:
In the Vishay transceiver data sheets the following
nomenclature is used for defining the IrDA operating modes:
SIR: 2.4 kbit/s to 115.2 kbit/s, equivalent to the basic serial
infrared standard with the physical layer version IrPhy 1.0
MIR: 576 kbit/s to 1152 kbit/s
FIR: 4 Mbit/s
VFIR: 16 Mbit/s
MIR and FIR were implemented with IrPhy 1.1, followed by
IrPhy 1.2, adding the SIR low power standard. IrPhy 1.3
extended the low power option to MIR and FIR and VFIR was
added with IrPhy 1.4. A new version of the standard in any
case obsoletes the former version.
With introducing the updated versions the old versions are
obsolete. Therefore the only valid IrDA standard is the actual
version IrPhy 1.4 (in Oct. 2002).
PIN DESCRIPTION
PIN NUMBER FUNCTION DESCRIPTION I/O ACTIVE

V
CC2
IRED anode
Connect IRED anode directly to the power supply (V
CC2
). IRED current can be
decreased by adding a resistor in series between the power supply and IRED
anode. A separate unregulated power supply can be used at this pin.
2 IRED cathode IRED cathode, internally connected to the driver transistor.
3TXD
This Schmitt-Trigger input is used to transmit serial data when SD is low. An
on-chip protection circuit disables the LED driver if the TXD pin is asserted for
longer than 100 µs. The input threshold voltage adapts to and follows the logic
voltage swing defined by the applied supply voltage.
IHigh
4RXD
Received data output, push-pull CMOS driver output capable of driving
standard CMOS or TTL loads. During transmission the RXD output is active
and mirrors the transmit signal. No external pull-up or pull-down resistor is
required. Floating with a weak pull-up of 500 kΩ (typ.) in shutdown mode. The
voltage swing is defined by the applied supply voltage.

swing defined by the applied supply voltage.

Note
Reference point ground (pin 8) unless otherwise noted.
Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
We apologize to use sometimes in our documentation the abbreviation LED and the word light emitting diode instead of infrared emitting diode
(IRED) for IR-emitters. That is by definition wrong; we are here following just a bad trend.
Typical values are for design aid only, not guaranteed nor subject to production testing and may vary with time.

Vishay transceivers operating inside the absolute maximum ratings are classified as eye safe according the above table.
