TSOP91..
Vishay Semiconductors
IR Receiver Modules for Remote Control Systems
Description
The TSOP91.. - 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 of the
TSOP91.. is the compatibility to all kind of datafor-
mats.

TSOP91..
Vishay Semiconductors
Suitable Data Format
The circuit of the TSOP91.. is designed in that way
that unexpected output pulses due to noise or distur-
bance signals are avoided. A bandpass filter, an inte-
grator 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 6 cycles/burst or longer.
• After each burst which is between 6 cycles and 70
cycles a gap time of at least 10 cycles is necessary.
• For each burst which is longer than 1.8 ms a corre-
sponding gap time is necessary at some time in the
data stream. This gap time should have at least same
length as the burst.
• Up to 2200 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, RECS-80
Code.
When a disturbance signal is applied to the TSOP91..
it can still receive the data signal. However the sensi-
tivity is reduced to such a level that no unexpected
pulses will occur.
Some examples for such disturbance signals which
are suppressed by the TSOP91.. 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 (an example of the signal modulation is shown in
Figure 13).
