Manufacturer:MAX Description:The circuit of the TSOP22..YA1 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 dis- turbance signal are carrier frequency, burst length and duty cycle. The data signal should fulfill the following conditions: • Carrier frequency should be close to center fre- quency of the bandpass (e.g. 38 kHz). • 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 necessary. • For each burst which is longer than 1.8 ms a corre- sponding 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, Sony Code. When a disturbance signal is applied to the TSOP22..YA1 it can still receive the data signal. How- ever the sensitivity is reduced to that level that no unexpected pulses will occure. Some examples for such disturbance signals which are suppressed by the TSOP22..YA1 are: • DC light (e.g. from tungsten bulb or sunlight) • Continuous signal at 38 kHz or at any other fre- quency |
