| VISHAY TSOP11..TB1 Vishay Semiconductors IR Receiver Modules for Remote Control Systems Description The TSOP11..TB1 - 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 operation with short burst transmission codes and high data rates.

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 fulfill the following conditions: * Carrier frequency should be close to center frequency of the bandpass (e.g. 38 kHz). * Burst length should be 6 cycles/burst or longer. * After each burst which is between 6 cycles and 70 cycles a gap time of at least 10 cycles is necessary. * For each burst which is longer than 1.8 ms a corresponding gap time is necessary at some time in the 850 950 1050 1150 94 8408 l - Wavelength ( nm ) Figure 11. Relative Spectral Sensitivity vs. Wavelength Document Number 82011 Rev. 11, 15-Oct-2002 www.vishay.com 4 VISHAY data stream. This gap time should have at least same length as the burst. * Up to 2200 short bursts per second can be received continuously. Some examples for suitable data format are: NEC Code, Toshiba Micom Format, Sharp Code, RC5 Code, RC6 Code, RCMM Code, R-2000 Code, RECS-80 Code. When a disturbance signal is applied to the TSOP11..TB1 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 TSOP11..TB1 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 (an example of the signal modulation is in the figure below).

Meet all present and future national and international statutory requirements. VISHAY 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.
