Vishay Semiconductors
Infrared Transceiver Module (SIR, 115.2 kbit/s)
for IrDA^® Applications
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
20110
the optical input pulse duration and recovers always a
fixed pulse duration optimum for compatibility to
standard Endecs and interfaces. TFDU4101 has a tri-
state output and is floating in shutdown mode with a
weak pull-up.
Features

specification over full temperature range
from - 30 °C to + 85 °C
• Split power supply, transmitter and
e3
receiver can be operated from two power
supplies with relaxed requirements saving costs,
