Infrared Transceiver Module (SIR, 115.2 kbit/s)
for IrDA® Applications
20101
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.
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
• Internet TV boxes, video conferencing systems
• External infrared adapters (dongles)
• Data loggers
• GPS
• Kiosks, POS, point and pay devices including
IrFM - applications
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
• Split power supply, transmitter and receiver can
be operated from two power supplies with
relaxed requirements saving costs, US patent
no. 6.157.476

• Surface mount package
• 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 or TOIM5232
• 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
• Qualified for lead (Pb)-free and Sn/Pb processing (MSL4)
• Compliant to RoHS directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
