Infrared Transceiver Module (SIR, 115.2 kbit/s)

for IrDA

Applications

Description

The TFDU4300 is a low profile (2.5 mm) infrared

transceiver module with independent logic reference

voltage (V

logic

) for low voltage IO interfacing. 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.

This Vishay SIR transceiver is built in a new smaller

package using the experiences of the lead frame

BabyFace technology.

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. TFDU4300 has a tri-state output

and is floating in shut-down mode with a weak pull-up.

Features

• Compliant to the latest IrDA physical

layer specification (9.6 kbit/s to

115.2 kbit/s) and TV Remote Control,

bi-directional operation included.

specification over full temperature range

from - 30 °C to + 85 °C

• Logic voltage 1.5 V to 5.5 V is independent of

IRED driver and analog supply voltage

• Split power supply, transmitter and receiver can be

operated from two power supplies with relaxed

requirements saving costs, US patent

• no. 6.157.476

• Extended IrDA low power range to about 70 cm

• Typical remote control range 12 m

• High efficiency emitter

• Low profile (universal) package capable of surface

mount soldering to side and top view orientation

WEEE 2002/96EC

Applications

• Ideal for battery operated applications

• Telecommunication products (cellular phones,

pagers)

• Digital still and video cameras

• Printers, fax machines, photocopiers, screen

projectors

• Medical and industrial data collection

IRED anode

Connect IRED anode directly to the power supply (V

). 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.

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 300 μs. The input threshold

voltage adapts to and follows the logic voltage swing defined by the

applied V

logic

voltage.

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).

Absolute Maximum Ratings

Reference point ground (pin 8) unless otherwise noted.

Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

Note: 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.

Eye Safety Information

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

following table.
