TSOP15.. Vishay Telefunken Photo Modules for PCM Remote Control Systems Available types for different carrier frequencies Type TSOP1530 TSOP1536 TSOP1538 TSOP1556 fo 30 kHz 36 kHz 38 kHz 56 kHz Type TSOP1533 TSOP1537 TSOP1540 fo 33 kHz 36.7 kHz 40 kHz Description The TSOP15.. – 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.

Vishay Telefunken Suitable Data Format The circuit of the TSOP15.. 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 and disturbance signal are carrier frequency, burst length and duty cycle. 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 10 cycles/burst or longer. • After each burst which is between 10 cycles and 70 cycles a gap time of at least 14 cycles is neccessary. • For each burst which is longer than 1.8ms a corresponding gap time is necessary at some time in the data stream. This gap time should be at least 4 times longer than the burst. • Up to 800 short bursts per second can be received continuously. Some examples for suitable data format are: NEC Code (repetitive pulse), NEC Code (repetitive data), Toshiba Micom Format, Sharp Code, RC5 Code, RC6 Code, R–2000 Code. When a disturbance signal is applied to the TSOP15.. 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 TSOP15.. are: • DC light (e.g. from tungsten bulb or sunlight) • Continuous signal at 38kHz or at any other frequency • Signals from fluorescent lamps with electronic ballast with high or low modulation (see Figure A or Figure B). 0 5 10 time [ms] 15 20 Figure A: IR Signal from Fluorescent Lamp with low Modulation 0 5 10 time [s] 15 20 Figure B: IR Signal from Fluorescent Lamp with high Modulation Document Number 82029 Rev. 9, 30-Mar 01 www.vishay.com 3 (7) TSOP15..
