Description

The TSOP18.. – series are miniaturized receivers forinfrared remote control systems. PIN diode and pre-amplifier are assembled on lead frame, the epoxypackage is designed as IR filter.The demodulated output signal can directly be de-coded by a microprocessor. The main benefit is thereliable function even in disturbed ambient and theprotection against uncontrolled output pulses.

Suitable Data FormatThe circuit of the TSOP18... is designed in that waythat unexpected output pulses due to noise ordisturbance signals are avoided. A bandpassfilter, an

integrator stage and an automatic gain control areused to suppress such disturbances.The distinguishing mark between data signal ( notsuppressed) and disturbance signal (supressed) arecarrier frequency, burst length and Signal Gap Time(see diagram below).

The data signal should fullfill the following condition:

• Carrier frequency should be close to center fre-quency of the bandpass (e.g. 38kHz).

• Burst length should be 6 cycles/burst or longer.

• After each burst a gap time of at least 9 cycles is

neccessary.• The data format should not make a continuoussignal transmission. There must be a Signal Gap Time(longer than 14ms) at least each 90ms

Some examples for suitable data format are:NEC Code (repetitive pulse), NEC Code (repetitivedata), Toshiba Micom Format, Sharp Code, RC5

Code, RECS–80 Code, R–2000 Code.

When a disturbance signal is applied to the TSOP18...it can still receive the data signal. However thesensitivity is reduced to that level that no unexpectedpulses will occure.

Some examples for such disturbance signals whichare suppressed by the TSOP18... are:

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

• Continuous signal at 38kHz or at any other

frequency,

• Signals from fluorescent lamps.

• Continuous IR signal (e.g. 1ms burst, 2ms pause)

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 theirimpact on the environment.

It is particular concern to control or eliminate releases of those substances into the atmosphere which are known asozone depleting substances (ODSs).

The Montreal Protocol (1987 ) and its London Amendments (1990) intend to severely restrict the use of ODSs andforbid their use within the next ten years. Various national and international initiatives are pressing for an earlier banon these substances.

Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use ofODSs 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 EnvironmentalProtection 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 depletingsubstances 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 applicationby 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 orindirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
