Relaive Specral Sensiiviy vs. Wavelengh Suiable Daa Forma The circui of he TSOP1.. is designed in ha way ha unexpeced oupu pulses due o noise or disurbance signals are avoided. A bandpassfiler, an inegraor sage and an auomaic gain conrol are used o suppress such disurbances. The disinguishing mark beween daa signal and disurbance signal are carrier frequency, burs lengh and duy cycle. The daa signal should fulfill he following condiions: Carrier frequency should be close o cener frequency of he bandpass (e.g. 38 khz). Burs lengh should be 10 cycles/burs or longer. Afer each burs which is beween 10 cycles and 70 cycles a gap ime of a leas 14 cycles is necessary. For each burs which is longer han 1.8 ms a corresponding gap ime is necessary a some ime in he 4
TSOP1.. daa sream. This gap ime should be a leas 4 imes longer han he burs. Up o 800 shor burss per second can be received coninuously. Some examples for suiable daa forma are: NEC Code (repeiive pulse), NEC Code (repeiive daa), Toshiba Micom Forma, Sharp Code, RC5 Code, RC6 Code, R-000 Code, Sony Code. When a disurbance signal is applied o he TSOP1.. i can sill receive he daa signal. However he sensiiviy is reduced o ha level ha no unexpeced pulses will occure. Some examples for such disurbance signals which are suppressed by he TSOP1.. are: DC ligh (e.g. from ungsen bulb or sunligh) Coninuous signal a 38 khz or a any oher frequency Signals from fluorescen lamps wih elecronic ballas wih high or low modulaion (see Figure 14 or Figure 15).

I is paricular concern o conrol or eliminae releases of hose subsances ino he amosphere which are known as ozone depleing subsances (ODSs). The Monreal Proocol (1987) and is London Amendmens (1990) inend o severely resric he use of ODSs and forbid heir use wihin he nex en years. Various naional and inernaional iniiaives are pressing for an earlier ban on hese subsances. Vishay Semiconducor GmbH has been able o use is policy of coninuous improvemens o eliminae he use of ODSs lised in he following documens. 1.
