Description

The TSOP12..KA1 – 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. The main benefit is the

reliable function even in disturbed ambient and the

protection against uncontrolled output pulses.

Suitable Data Format

The circuit of the TSOP12..KA1 is designed in that way

•

Up to 800 short bursts per second can be received

that unexpected output pulses due to noise or continuously.

disturbance signals are avoided. A bandpassfilter, an

Some examples for suitable data format are:

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.

NEC Code (repetitive pulse), NEC Code (repetitive

data), Toshiba Micom Format, Sharp Code, RC5

Code, RC6 Code, R–2000 Code.

When a disturbance signal is applied to the

TSOP12..KA1 it can still receive the data signal.

However the sensitivity is reduced to that level that no

unexpected pulses will occure.

The data signal should fullfill the following condition:

•

Carrier frequency should be close to center

frequency of the bandpass (e.g. 38kHz).

Some examples for such disturbance signals which

are suppressed by the TSOP12..KA1 are:

•

Burst length should be 10 cycles/burst or longer.

After each burst which is between 10 cycles and 70

•

DC light (e.g. from tungsten bulb or sunlight)

cycles a gap time of at least 14 cycles is neccessary.

•

Continuous signal at 38kHz or at any other

frequency

•

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 ballast with high or low modulation (see Figure A or

times longer than the burst. Figure B).

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.
