Definitions:
In the Vishay transceiver datasheets 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.

(4) Maximum irradiance E in angular range, power per unit area. The optical delivered to the detector by a source operating at the maximum

RECOMMENDED CIRCUIT DIAGRAM
Operated at a clean low impedance power supply the
TFBS4650 needs only one additional external component
when the IRED drive current should be minimized for
minimum current consumption according the low power IrDA
standard. When combined operation in IrDA and remote
control is intended no current limiting resistor is
recommended.
However, depending on the entire system design and board
layout, additional components may be required (see fig. 1).
When long wires are used for bench tests, the capacitors are
mandatory for testing rise/fall time correctly.

depend on the quality of the supply voltages VCCx and
injected noise. An unstable power supply with dropping
voltage during transmission may reduce the sensitivity (and
transmission range) of the transceiver.
The placement of these parts is critical. It is strongly
recommended to position C2 as close as possible to the
transceiver power supply pins.
When connecting the described circuit to the power supply,
low impedance wiring should be used.
In case of extended wiring the inductance of the power
supply can cause dynamically a voltage drop at VCC2. Often
some power supplies are not able to follow the fast current is
rise time. In that case another 10 µF cap at VCC2 will be
helpful.
Keep in mind that basic RF-design rules for circuit design
should be taken into account. Especially longer signal lines
should not be used without termination. See e.g. “The Art of
Electronics” Paul Horowitz, Wienfield Hill, 1989, Cambridge
University Press, ISBN: 0521370957.

See table 3
The capacitor C1 is buffering the supply voltage VCC2 and
eliminates the inductance of the power supply line. This one
should be a small ceramic version or other fast capacitor to
guarantee the fast rise time of the IRED current. The resistor
R1 is necessary for controlling the IRED drive current when
the internally controlled current is too high for the application.
Vishay transceivers integrate a sensitive receiver and a
built-in power driver. The combination of both needs a
careful circuit board layout. The use of thin, long, resistive
and inductive wiring should be avoided. The inputs (TXD,
SD) and the output RXD should be directly (DC) coupled to
the I/O circuit.
The capacitor C2 combined with the resistor R2 is the low
pass filter for smoothing the supply voltage.
As already stated above R2, C1 and C2 are optional and

Fig. 2 - Recommended Solder Profile for Sn/Pb Soldering
Fig. 3 - Solder Profile, RSS Recommendation
Lead (Pb)-free, Recommended Solder Profile
The TFBS4650 is a lead (Pb)-free transceiver and qualified
for lead (Pb)-free processing. For lead (Pb)-free solder paste
like Sn(3.0 - 4.0)Ag (0.5 - 0.9)Cu, there are two standard reflow
profiles: Ramp-Soak-Spike (RSS) and Ramp-To-Spike
(RTS). The Ramp-Soak-Spike profile was developed
primarily for reflow ovens heated by infrared radiation. With
widespread use of forced convection reflow ovens the
Ramp-To-Spike profile is used increasingly. Shown in
figure 3 is Vishay’s recommended profiles for use with the
TFBS4650 transceivers. For more details please refer to the
application note “SMD Assembly Instructions”.
Wave Soldering
For TFDUxxxx and TFBSxxxx transceiver devices wave
soldering is not recommended.
Manual Soldering
Manual soldering is the standard method for lab use.
However, for a production process it cannot be
recommended because the risk of damage is highly
dependent on the experience of the operator. Nevertheless,
we added a chapter to the above mentioned application note,
describing manual soldering and desoldering.
Storage
The storage and drying processes for all Vishay transceivers
(TFDUxxxx and TFBSxxx) are equivalent to MSL4.
The data for the drying procedure is given on labels on the
packing and also in the application note “Taping, Labeling,
Storage and Packing”.
