Fast Infrared Transceiver Module (4 Mbit/s), IrDA
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-
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
demodulation function. At a minimum, a V
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.

The default mode of the TFDU6108 is different from the originally defined IrDA Serial Interface default mode.
