TFDU6108
Vishay Semiconductors
Fast Infrared Transceiver Module (4 Mbit/s), IrDA® Serial
Interface Compatible, 2.7 V to 5.5 V Supply Voltage Range
Description
The TFDU6108 is an infrared transceiver module
compliant to the latest IrDA standard for fast infrared
data communication, supporting IrDA speeds up to
4.0 Mbit/s (FIR), and carrier based remote control
modes up to 2 MHz. Integrated within the transceiver
module are a PIN photodiode, an infrared emitter
(IRED), and a low-power CMOS control IC to provide
a total front-end solution in a single package.
These FIR transceivers with an integrated serial inter-
18102
face are compliant with the IrDA "Serial Interface
Standard for Transceiver Control". The transceivers
are capable of directly interfacing with a wide variety
of I/O devices, which perform the modulation/
demodulation function. At a minimum, a VCC bypass
capacitor is the only external component required
implementing a complete solution. For limiting the
transceiver internal power dissipation one additional
resistor might be added. The transceiver can be oper-
ated with logic I/O voltages as low as 1.5 V.
New Features
⢠The functionality of the device is similar to the
TFDU6102 series. The IrDA compatible serial
interface function is replacing the former program-
ming method, guaranteeing a perfect IrDA stan-
dardized and compliant programmability. The
IRED current is programmable to different levels,
no external current limiting resistor is necessary.
