DESCRIPTION
These products are miniaturized receivers for low speed
infrared data transmission. A PIN diode and a preamplifier
are assembled on a lead frame, the epoxy package contains
an IR filter.
The demodulated output can be directly connected to a
UART or a microprocessor. The TSDP34138 may be used
for continuous reception of data according to RS-232 at
4800 bps in noise free environments. Higher data rate
RS-232 may require data monitoring of gain levels. Non
RS-232 codings may be used to achieve continuous
average data rates up to 7800 bps in noisy ambients.
This component has not been qualified according to
automotive specifications.

SUITABLE DATA FORMAT
Theses receivers are designed to suppress spurious output
pulses due to noise or optical disturbances. The devices can
distinguish data signals from noise due to differences in
frequency, burst length, and envelope duty cycle. For
optimum sensitivity, the data’s modulation frequency
should be close to the device’s band-pass center frequency
(e.g. 38.4 kHz) and fulfill the conditions in the table below.
When a data signal is applied to the receiver in the presence
of noise, the sensitivity of the receiver is automatically
reduced by the AGC to insure that no spurious pulses are
present at the receiver’s output. Some examples of noise
which is suppressed:
DC light (e.g. from tungsten bulbs sunlight)
Continuous signals at any frequency
• Strongly or weakly modulated patterns from fluorescent
lamps with electronic ballasts (see Fig. 13 or Fig. 14).
