Photo Modules for PCM Remote Control Systems
Available types for different carrier frequencies
Type TSOP1830 TSOP1836 TSOP1838 TSOP1856 fo 30 kHz 36 kHz 38 kHz 56 kHz Type TSOP1833 TSOP1837 TSOP1840 fo 33 kHz 36.7 kHz 40 kHz
Description
The TSOP18.. 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 reliable function even in disturbed ambient and the protection against uncontrolled output pulses.

TSOP18..
Vishay Telefunken Suitable Data Format
The circuit of the TSOP18.. 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 ( not suppressed) and disturbance signal (supressed) are carrier frequency, burst length and Signal Gap Time (see diagram below). 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 6 cycles/burst or longer. · After each burst a gap time of at least 9 cycles is neccessary. · The data format should not make a continuous signal transmission. There must be a Signal Gap Time (longer than 15ms) at least each 90ms (see Figure A). Some examples for suitable data format are: NEC Code (repetitive pulse), NEC Code (repetitive data), Toshiba Micom Format, Sharp Code, RC5 Code, RECS80 Code, R2000 Code. When a disturbance signal is applied to the TSOP18.. 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 TSOP18.. are: · DC light (e.g. from tungsten bulb or sunlight), · Continuous signal at 38kHz or at any other frequency, · Signals from fluorescent lamps (see Figure B). · Continuous IR signal (e.g. 1ms burst, 2ms pause)
