Description
The TSOP13.. 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.

Suitable Data Format
The circuit of the TSOP13.. 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. 38kHz).
Burst length should be 6 cycles/burst or longer.
After each burst which is between 6 cycles and 70
cycles a gap time of at least 12 cycles is neccessary.
For each burst which is longer than 1.2ms a
corresponding gap time is necessary at some time in
the data stream. This gap time should be at least 6
times longer than the burst.
Up to 1000 short bursts per second can be received
continuously.
Some examples for suitable data format are:
NEC Code, Toshiba Micom Format, Sharp Code, RC5
Code, RECS80 Code, R2000 Code.
When a disturbance signal is applied to the TSOP13..
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 TSOP13.. are:
DC light (e.g. from tungsten bulb or sunlight)
Continuous signal at 38kHz or at any other
frequency
Signals from fluorescent lamps with electronic
ballast with high or low modulation (see Figure A or
Figure B).
