IR Receiver Modules for Remote Control Systems
Description
The TSOP312.. - 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. TSOP312.. is the standard IR remote control receiver series for 3 V supply
voltage, supporting all major transmission codes.

TSOP312..
Vishay Semiconductors
Suitable Data Format
The circuit of the TSOP312.. is designed in that way
that unexpected output pulses due to noise or disturbance signals are avoided. A bandpass filter, an integrator stage and an automatic gain control are used
to suppress such disturbances.
The distinguishing mark between data signal and disturbance signal are carrier frequency, burst length
and duty cycle.
The data signal should fulfill the following conditions:
• Carrier frequency should be close to center frequency of the bandpass (e.g. 38 kHz).
• Burst length should be 10 cycles/burst or longer.
• After each burst which is between 10 cycles and 70
cycles a gap time of at least 14 cycles is necessary.
• For each burst which is longer than 1.8 ms 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.
Some examples for suitable data format are: NEC
Code (repetitive pulse), NEC Code (repetitive data),
Toshiba Micom Format, Sharp Code, RC5 Code,
RC6 Code, R-2000 Code, Sony Code.
When a disturbance signal is applied to the
TSOP312.. it can still receive the data signal. However the sensitivity is reduced to that level that no
unexpected pulses will occur.
Some examples for such disturbance signals which
are suppressed by the TSOP312.. are:
• DC light (e.g. from tungsten bulb or sunlight)
• Continuous signal at 38 kHz or at any other frequency
• Signals from fluorescent lamps with electronic ballast with high or low modulation
( see Figure 15 or Figure 16 ).

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
operatingsystems 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 Semiconductors products for any
unintended or unauthorized application, the buyer shall indemnify Vishay Semiconductors 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.
