Description

The TSOP1 1..XG1 – 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 short burst transmission codes (e.g.
RECS 80) and high data rates.

Suitable Data Format

The circuit of the TSOP11..XG1 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 necces
sary.

• 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
TSOP11..XG1 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 TSOP11..XG1 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 in
the figure below).
