Suitable Data Format

The circuit of the TSOP52.. is designed in that way that unexpected output pulses due to noise or disturbance signals are avoided. A bandpassfilter, 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 fullfill the following condition:

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

•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 1.8ms 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.

TSOP52..

Vishay Telefunken

Some examples for suitable data format are: NEC Code, T oshiba Micom Format, Sharp Code, RC5 Code, RC6 Code, R–2000 Code.

When a disturbance signal is applied to the TSOP52.. it can still receive the data signal. However the sensitivity is reduced to that level that no unexpected pulses will occure.

Some examples for such disturbance signals which are suppressed by the TSOP52.. are:

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

•Continuous signal at 38kHz or at any other

frequency

•Signals from fluorescent lamps with electronic ballast with high or low modulation (see Figure A or Figure B).

Operating Instructions

Reflow Soldering

D Reflow soldering must be done within 48 hours

stored under max. 30°C, 80% RH after opening envelop

D Recommended soldering paste

(composition: SN 63%, Pb 37%) Melting temperature 178 to 192°C

D Apply solder paste to the specified soldering

pads, by using a dispenser or by screen printing.

D Recommended thickness of metal mask is 0.2 mm

for screen printing.

D The recommended reflow furnace is a

combinationtype with upper and lower heaters.

D Set the furnace temperatures for pre-heating and

heating in accordance with the reflow temperature profile as shown below. Excercise extreme care to keep the maximum temperature below 230_C. The following temperature profile means the tempera– ture at the device surface. Since temperature differ– ence occurs between the work and the surface of the circuit board depending on the pes of circuit board or reflow furnace, the operating conditions should be verified prior to start of operation.

D Handling after reflow should be done only after the

work surface has been cooled off.

Manual Soldering

D Use the 6/4 solder or the solder containing silver. D Use a soldering iron of 25 W or smaller. Adjust the

temperature of the soldering iron below 300_C. D Finish soldering within three seconds. D Handle products only after the temperature is

cooled off.

Cleaning

D Perform cleaning after soldering strictly in

conformance to the following conditions:

Cleaning agent:

2-propanol (isopropyl alcohol). Commercially available grades (industrial use) should be used. Demineralized or distilled water having a resistivity of not less than 500 m corresponding to a conductivity of 2 mS/m.

D Temperature and time: 30 seconds under the

temperature below 50_C or 3 minutes below 30_C. D Ultrasonic cleaning: Below 20 W.

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 V ishay-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.
