Description
The TSOP18.. 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 TSOP18.. 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 ( not
suppressed) and disturbance signal (supressed) are
carrier frequency, burst length and Signal Gap Time
(see diagram below).
The data signal should fullfill the following condition:
Carrier frequency should be close to center fre-
quency of the bandpass (e.g. 38kHz).
Burst length should be 6 cycles/burst or longer.
After each burst a gap time of at least 9 cycles is
neccessary.
The data format should not make a continuous
signal transmission. There must be a Signal Gap Time
(longer than 15ms) at least each 90ms (see Figure A).
Some examples for suitable data format are:
NEC Code (repetitive pulse), NEC Code (repetitive
data), Toshiba Micom Format, Sharp Code, RC5
Code, RECS80 Code, R2000 Code.
When a disturbance signal is applied to the TSOP18..
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 TSOP18.. are:
DC light (e.g. from tungsten bulb or sunlight),
Continuous signal at 38kHz or at any other
frequency,
Signals from fluorescent lamps (see Figure B).
Continuous IR signal (e.g. 1ms burst, 2ms pause)
