Serial Infrared Transceiver
SIR, 115.2 kbit/s, 2.7 V to 5.5 V Operation
DescriptionThe TFDU4100 is a part of the 4000 – family of low –
current consumption infrared transceiver modules
compliant to the IrDA standard for serial infrared (SIR)
data communication, supporting IrDA speeds up to
115.2 kbit/s. Integrated within the transceiver modules
are a photo PIN diode, infrared emitter (IRED), and a
low–power analog control IC to provide a total
front–end solution in a single package. The
transceivers are capable of directly interfacing with a
wide variety of I/O chips which perform the
pulse–width modulation/demodulation function,
including Vishay Semiconductors’ TOIM4232. At a
minimum, a current– limiting resistor in series with the
infrared emitter and a VCC bypass capacitor are the
only external components required to implement a
complete solution.
Features Compliant to the latest IrDA physical layer
specification (Up to 115.2 kbit/s),
