Description
The TSOP51.. – series are miniaturized SMD–IR
Receiver Modules 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. TSOP51.. is the
standard IR remote control SMD–Receiver series,
supporting all major transmission codes.

Suitable Data Format
The circuit of the TSOP51.. 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:
D
Carrier frequency should be close to center
frequency of the bandpass (e.g. 38kHz).
D
Burst length should be 6 cycles/burst or longer.
D
After each burst which is between 6 cycles and
70 cycles a gap time of at least 10 cycles is
neccessary.
D
For each burst which is longer than 1.8 ms 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.
D
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 TSOP51..
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 TSOP51.. are:
D
DC light (e.g. from tungsten bulb or sunlight)
D
Continuous signal at 38kHz or at any other
frequency
D
Signals from fluorescent lamps with electronic
ballast (an example of the signal modulation is in
the figure below).
