Suitable Data Format
The circuit of the TSOP22..KU1 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. 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
neccessary.
For each burst which is longer than 1.8 ms 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, Toshiba Micom Format, Sharp Code,
RC5 Code, RC6 Code, R–2000 Code.
When a disturbance signal is applied to the
TSOP22..KU1 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 TSOP22..KU1 are:
DC light (e.g. from tungsten bulb or sunlight)
Continuous signal at 38 kHz or at any other
frequency
Signals from fluorescent lamps with electronic
ballast with low modulation
(see Figure A or Figure B).
