Photo Modules for PCM Remote Control Systems
Description
The HS0038A2. – series are miniaturized receivers for
infrared remote control systems. PIN diode and
preamplifier are assembled on lead frame, the epoxy
package is designed as IR filter.
The demodulated output signal can directly be
decoded by a microprocessor. HS0038A2. is the
standard IR remote control receiver series, supporting
all major transmission codes.

Suitable Data Format
The circuit of the HS0038A2. is designed in that way Some examples for suitable data format are:
that unexpected output pulses due to noise or NEC Code (repetitive pulse), NEC Code (repetitive
disturbance signals are avoided. A bandpassfilter, an data), Toshiba Micom Format, Sharp Code
integrator stage and an automatic gain control are
When a disturbance signal is applied to the
used to suppress such disturbances.
HS0038A2. it can still receive the data signal. However
The distinguishing mark between data signal and
the sensitivity is reduced to that level that no unex-
disturbance signal are carrier frequency, burst length
pected pulses will occure.
and duty cycle.
Some examples for such disturbance signals which
are suppressed by the HS0038A2. are:
The data signal should fullfill the following condition:
•
•
•
Carrier frequency should be close to 38kHz.
Burst length should be 10 cycles/burst or longer.
•
•
DC light (e.g. from tungsten bulb or sunlight)
Continuous signal at 38kHz or at any other
frequency
After each burst which is between 10 cycles and
70 cycles a gap time of at least 14 cycles is
neccessary.
•
Signals from fluorescent lamps with electronic
ballast with low modulation (see Figure A or B).
•
•
For each burst which is longer than 1.8ms a
corresponding gap time is necessary at some
time in the data stream. This gap time should be
at least 4 times longer than the burst.
Up to 800 short bursts per second can be
received continuously.

Ozone Depleting Substances Policy Statement
It is the policy of Vishay Semiconductor GmbH to
1. Meet all present and future national and international statutory requirements.
2. Regularly and continuously improve the performance of our products, processes, distribution and operating
systems with respect to their impact on the health and safety of our employees and the public, as well as their
impact on the environment.
It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as
ozone depleting substances (ODSs).
The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs and
forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban
on these substances.
Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of
ODSs listed in the following documents.
1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively
2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental
Protection Agency (EPA) in the USA
3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively.
Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting
substances and do not contain such substances.
We reserve the right to make changes to improve technical design and may do so without further notice.
Parameters can vary in different applications. All operating parameters must be validated for each customer application
by the customer. Should the buyer use Vishay-Telefunken products for any unintended or unauthorized application, the
buyer shall indemnify Vishay-Telefunken against all claims, costs, damages, and expenses, arising out of, directly or
indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
