TSOP69..
Vishay Semiconductors
IR Receiver Modules for Remote Control Systems
Description
The TSOP69.. - 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
operation with a high envelope duty cycle datasignal
and the good immunity against disturbance signals
with spike characteristic as well as all continuous dis-
turbance signals.

Suitable Data Format
The circuit of the TSOP69.. is designed in that way
that unexpected output pulses due to noise or distur-
bance signals are avoided. A bandpass filter, a limiter
stage, an integrator stage and an automatic gain con-
trol 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 120
cycles a gap time of at least 10 cycles is necessary.
• For each burst which is longer than 3.2 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, Toshiba Micom Format, Sharp Code, RC5
Code, RC6 Code, RCMM Code, R-2000 Code,
RECS-80 Code.
When a disturbance signal is applied to the TSOP69..
it can still receive the data signal. However the sensi-
tivity is reduced to that level that no unexpected
pulses will occur.
Some examples for such disturbance signals which
are suppressed by the TSOP69.. 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-
lasts with various kinds of modulation
(see examples in Figure 13 and Figure 14).

Standard bar code labels for finished goods
The standard bar code labels are product labels and
used for identification of goods. The finished goods
are packed in final packing area. The standard pack-
ing units are labeled with standard bar code labels
before transported as finished goods to warehouses.
The labels are on each packing unit and contain
Vishay Semiconductor GmbH specific data.
