Description
The TSOP17..GL1 – 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. TSOP17.... is the
standard IR remote control receiver series, supporting all major transmission codes.

Suitable Data Format
The circuit of the TSOP17..GL1 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:
TSOP17..GL1
Vishay Telefunken
Some examples for suitable data format are: NEC Code, T oshiba Micom Format, Sharp Code, RC5 Code, RC6 Code, R–2000 Code, Sony Format (SIRCS).
When a disturbance signal is applied to the TSOP17..GL1 it can still receive the data signal. However the sensitivity is reduced to that level that no unexpected pulses will occure.
Carrier frequency should be close to center frequency of the bandpass (e.g. 38kHz).
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 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 1400 short bursts per second can be received continuously .

Some examples for such disturbance signals which are suppressed by the TSOP17..GL1 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).
