Description
The TSOP21.. – 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
TSOP21..
Vishay Telefunken
The circuit of the TSOP21... 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 10 cycles is
neccessary.
• For each burst which is longer than 1.8ms a
corresponding 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, T oshiba Micom Format, Sharp Code, RC5
Code, RC6 Code, RCMM Code, R–2000 Code,
RECS–80 Code.
When a disturbance signal is applied to the TSOP21...
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 TSOP21... 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 (an example of the signal modulation is
shown in the figure below).
