Appendix
Application Hints
The TFDU4203 does not need any external
components when operated at a “clean“ power supply.
In a more noisy ambient it is recommended to add a
capacitor C1 (4.7 F Tantalum) and a resistor
R1 (
≤
3
)
for noise suppression. In addition the
capacitor is needed to prevent a pulse distortion when
the power supply is not able to generate the peak
currents or inductive wiring is used. A combination of
a tantalum with a ceramics capacitor will be efficient to
attenuate both, RF and LF if RF noise is present. The
value is dependent on the power supply quality. A good
choice is between 4.7 F and 10 F.

Shut down
To shut down the TFDU4103 into a standby mode the
SD pin has to be set active.
Latency
The receiver is in specified conditions after the defined
latency. In a UART related application after that time
(typically 50
μ
s) the receiver buffer of the UART must
be cleared. Therefore the transceiver has to wait at
least the specified latency after receiving the last bit
before starting the transmission to be sure that the
corresponding receiver is in a defined state.
For more application circuits, see IrDC Design Guide
and TOIM3...–series data.

This is a recommendation for a combination to start with to exclude power supply effects.
Optimum, from a costs point of view, to work without both.
