TFDU4300
Vishay Semiconductors
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 (Vlogic) 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.
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.

• Operates from 2.4 V to 5.5 V within
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
• Low power consumption (< 0.12 mA supply
current)

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.
• Power shutdown mode (< 5 µA shutdown current
in full temperature range, up to 85 °C)
• Surface mount package, low profile (2.5 mm)
- (L 8.5 mm × H 2.5 mm × W 2.9 mm)
• High efficiency emitter
• Low profile (universal) package capable of surface
mount soldering to side and top view orientation
• Directly interfaces with various super I/O and
controller devices as e.g. TOIM4232
• Tri-state-receiver output, floating in shut down with
a weak pull-up
• Compliant with IrDA background light specification
• EMI immunity in GSM bands > 300 V/m verified
• Lead (Pb)-free device
• Qualified for lead (Pb)-free and Sn/Pb processing
(MSL4)
• Device in accordance with RoHS 2002/95/EC and
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
• Diagnostic systems
• Notebook computers, desktop PCs, palmtop
computers (Win CE, Palm PC), PDAs
