TSOP18..RF1
Vishay Telefunken Suitable Data Format
The circuit of the TSOP18..RF1 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, RECS–80 Code, R–2000 Code. When a disturbance signal is applied to the TSOP18..RF1 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..RF1 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)
Special Features
D Small size package D Enhanced immunity against all kinds of disturbance light
D No occurrence of disturbance pulses at the outD Short settling time after power on (<200ms)
Description
The TSOP18..RF1 – 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.
