Infrared Transceiver Module (SIR, 115.2 kbit/s)
for IrDA^® Applications
20110
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)
• Compliant to RoHS directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
