1 IR Receiver Modules for Remoe Conrol Sysems Descripion The - series are miniaurized receivers for infrared remoe conrol sysems. PIN diode and preamplifier are assembled on lead frame, he epoxy package is designed as IR filer. The demodulaed oupu signal can direcly be decoded by a microprocessor. is he sandard IR remoe conrol receiver series, supporing all major ransmission codes Feaures Phoo deecor and preamplifier in one package Inernal filer for PCM frequency Improved shielding agains elecrical field disurbance TTL and CMOS compaibiliy Oupu acive low Low power consumpion Special Feaures Improved immuniy agains ambien ligh Suiable burs lengh 10 cycles/burs Block Diagram Inpu PIN AGC Band Pass Conrol Circui 30 kω Demodulaor 3 V S 1 OUT GND Pars Table TSOP4830 TSOP4833 TSOP4836 TSOP4837 TSOP4838 TSOP4840 TSOP4856 Par Applicaion Circui Transmier wih TSALxxxx TSOPxxxx Circui OUT GND 30 khz 33 khz 36 khz 36.7 khz 38 khz 40 khz 56 khz R 1 =100Ω C 1 = 4.7 µf Carrier Frequency µc +V S GND R 1 +C 1 recommended o suppress power supply disurbances.

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 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 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 are: DC ligh (e.g. from ungsen bulb or sunligh) Coninuous signal a 38 khz or a any oher frequency 4

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.. Regularly and coninuously improve he performance of our producs, processes, disribuion and operaingsysems 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 (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. Annex A, B and lis of ransiional subsances of he Monreal Proocol and he London Amendmens respecively. Class I and II ozone depleing subsances in he Clean Air Ac Amendmens of 1990 by he Environmenal Proecion Agency (EPA) in he USA 3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (ransiional subsances) respecively. Vishay Semiconducor GmbH can cerify ha our semiconducors are no manufacured wih ozone depleing subsances and do no conain such subsances. We reserve he righ o make changes o improve echnical design and may do so wihou furher noice. Parameers can vary in differen applicaions. All operaing parameers mus be validaed for each cusomer applicaion by he cusomer. Should he buyer use producs for any uninended or unauhorized applicaion, he buyer shall indemnify agains all claims, coss, damages, and expenses, arising ou of, direcly or indirecly, any claim of personal damage, injury or deah associaed wih such uninended or unauhorized use.
