Suitable Data Format
The circuit of the TSOP22..QJ1 is designed in that
way that unexpected output pulses due to noise or
disturbance signals are avoided. A bandpass filter, 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 1.0 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..QJ1 it can still receive the data signal. How-
ever the sensitivity is reduced to that level that no
unexpected pulses will occur.
Some examples for such disturbance signals which
are suppressed by the TSOP22..QJ1 are:
DC light (e.g. from tungsten bulb or sunlight)
Continuous signal at 38 kHz or at any other fre-
quency
Signals from fluorescent lamps with electronic bal-
last with high or low modulation
( see Figure 13 or Figure 14 ).
