Infrared Transceiver Module (SIR, 115.2 kbit/s)

for IrDA

Applications

DESIGN SUPPORT TOOLS

DESCRIPTION

The TFDU4101 transceiver is an infrared transceiver module

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 modes.

Integrated within the transceiver module are a photo pin

diode, an infrared emitter (IRED), and a low-power control IC

to provide a total front-end solution in a single package. This

device covers the full IrDA range of more than 1 m using the

internal intensity control. With one external current control

resistor the current can be adjusted for shorter ranges

saving operating current operating in IrDA low power mode.

This Vishay SIR transceiver is using the lead frame

technology.

The receiver output pulse duration is independent of the

optical input pulse duration and recovers always a fixed

pulse duration optimum for compatibility to standard

Endecs and interfaces. TFDU4101 has a tristate output and

is floating in shutdown mode with a weak pull-up.

FEATURES

• 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

• Low power consumption (< 0.12 mA supply current in

receive mode, no signal)

• Power shutdown mode (< 4 μA shutdown current in full

temperature range, up to 85 °C, < 10 nA at 25 °C)

• Surface-mount package (L x W x H in mm): 9.7 × 4.7 × 4

• 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

• Qualified for lead (Pb)-free and Sn/Pb processing (MSL4)

• Material categorization: for definitions of compliance

TFDU4101 www.vishay.com Vishay Semiconductors RECOMMENDED CIRCUIT DIAGRAM Operated with a clean low impedance power supply the TFDU4101 needs no additional external components. However, depending on the entire system design and board layout, additional components may be required (see figure 1). That is especially the case when separate power supplies are used for bench tests. When using compact wiring and regulated supplies as e. g. in phone applications in most cases no external components are necessary.
