8、unken3(7)Rev.5,29-Mar-Document Number 82088Suitable Data FormatThe circuit of the TSOP48.ON1 is designed in thatway that unexpected output pulses due to noise ordisturbance signals are avoided.A bandpassfilter,anintegrator stage and an automatic gain control areused to suppress such disturbances.The

9、 distinguishing mark between data signal anddisturbance signal are carrier frequency,burst lengthand duty cycle.The data signal should fullfill the following condition:Carrier frequency should be close to centerfrequency of the bandpass(e.g.38kHz).Burst length should be 10 cycles/burst or longer.Aft

10、er each burst which is between 10 cycles and 70cycles a gap time of at least 14 cycles is necessary.For each burst which is longer than 1.8ms acorresponding gap time is necessary at some time inthe data stream.This gap time should be at least 4times longer than the burst.Up to 800 short bursts per s

11、econd can be receivedcontinuously.Some examples for suitable data format are:NEC Code,Toshiba Micom Format,Sharp Code,RC5Code,RC6 Code,R2000 Code.When a disturbance signal is applied to theTSOP48.ON1 it can still receive the data signal.However the sensitivity is reduced to that level that nounexpec

12、ted pulses will occure.Some examples for such disturbance signals whichare suppressed by the TSOP48.ON1 are:DC light(e.g.from tungsten bulb or sunlight)Continuous signal at 38kHz or at any otherfrequencySignals from fluorescent lamps with electronicballast with high or low modulation(see Figure A or
