TFDU8108
Vishay Semiconductors
Very Fast Infrared Transceiver Module (VFIR, 16 Mbit/s), Serial
Interface Compatible, 2.7 V to 5.5 V Supply Voltage Range
Description
The TFDU8108 transceiver is part of a family of low-
power consumption infrared transceiver modules
compliant to the IrDA physical layer standard for VFIR
infrared data communication, supporting IrDA speeds
up to 16 Mbit/s (VFIR) and carrier based remote con-
trol modes up to 2 MHz. Integrated within the trans-
ceiver module are a PIN photodiode, an infrared
emitter (IRED), and a low-power BiCMOS control IC
to provide a total front-end solution in a single pack-
age.

Vishay Semiconductors VFIR transceivers are avail-
able in the BabyFace package. This provides flexibil-
ity for a variety of applications and space constraints.
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 limit-
ing the transceiver internal power dissipation one
additional resistor might be necessary. The trans-
ceiver can be operated with logic I/O voltages as low
as 1.5 V. The functionality of the device is equivalent
to the TFDU6108 with the VFIR functionality added.
The IRED current is programmable to different levels,
no external current limiting resistor is necessary.

Definitions:
In the Vishay transceiver data sheets the following nomenclature is
used for defining the IrDA operating modes:
SIR: 2.4 kbit/s to 115.2 kbit/s, equivalent to the basic serial infrared
standard with the physical layer version IrPhy 1.0
MIR 576 kbit/s to 1152 kbit/s
FIR 4 Mbit/s
VFIR 16 Mbit/s
MIR and FIR were implemented with IrPhy 1.1, followed by IrPhy
1.2, adding the SIR Low Power Standard. IrPhy 1.3 extended the
Low Power Option to MIR and FIR and VFIR was added with IrPhy
1.4. A new version of the standard in any case obsoletes the former
version.
Remark:
Throughout the documentation the not correct term LED (Light
Emitting Diode) is used for Infrared Emitting Diode (IRED). We are
following the trend to use the term light for infrared radiation, which
is wrong but common usage.
