Vishay Semiconductors
IR Receiver Modules for Remote Control Systems
Description
The TSOP382.. - 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. TSOP382.. is the stan-
dard IR remote control receiver series, supporting all
major transmission codes.
This component has not been qualified according to
automotive specifications.

TSOP382..
Vishay Semiconductors
Suitable Data Format
The circuit of the TSOP382.. is designed so that unex-
pected output pulses due to noise or disturbance sig-
nals are avoided. A bandpass filter, an integrator
stage and an automatic gain control are used to sup-
press 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 1.8 ms a corre-
sponding gap time is necessary at some point 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
TSOP382.. it can still receive the data signal. How-
ever the sensitivity is reduced to such a level that no
unexpected pulses will occur.
Some examples for such disturbance signals which
are suppressed by the TSOP382.. 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).
