Suiable Daa Forma The circui of he TSOP22... 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 fullfill he following condiion: Carrier frequency should be close o cener frequency of he bandpass (e.g. 38kHz). Burs lengh should be 1 cycles/burs or longer. Afer each burs which is beween 1 cycles and 7 cycles a gap ime of a leas 14 cycles is neccessary. For each burs which is longer han 1.8ms a corresponding gap ime is necessary a some ime in he daa sream. This gap ime should be a leas 4 imes longer han he burs. Up o 8 shor burss per second can be received coninuously. Some examples for suiable daa forma are: NEC Code, Toshiba Micom Forma, Sharp Code, RC5 Code, RC6 Code, R 2 Code. When a disurbance signal is applied o he TSOP22... 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 TSOP22... are: DC ligh (e.g. from ungsen bulb or sunligh) Coninuous signal a 38kHz or a any oher frequency Signals from fluorescen lamps wih elecronic ballas wih high or low modulaion (see Figure A or Figure B). 5 1 15 2 ime [ms] Figure A: IR Signal from Fluorescen Lamp wih low Modulaion 5 1 15 2 ime [s] Figure B: IR Signal from Fluorescen Lamp wih high Modulaion Documen Number 8295 3 (7)

Ozone Depleing Subsances Policy Saemen I is he policy of Vishay Semiconducor GmbH o 1. Mee all presen and fuure naional and inernaional sauory requiremens. 2. Regularly and coninuously improve he performance of our producs, processes, disribuion and operaing sysems wih respec o heir impac on he healh and safey of our employees and he public, as well as heir impac on he environmen. 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 (199) 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.
