Description

The TSOP18..SS3VA – 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

The circuit of the TSOP18..SS3V A 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 ( not

suppressed) and disturbance signal (supressed) are

carrier frequency, burst length and Signal Gap Time

(see diagram below).

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 a gap time of at least 9 cycles is

neccessary.

• The data format should not make a continuous

signal transmission. There must be a Signal Gap Time

(longer than 25ms) at least each 150ms (see Figure A)

Some examples for suitable data format are:

NEC Code (repetitive pulse), NEC Code (repetitive

data), Toshiba Micom Format, Sharp Code, RC5

Code, RECS–80 Code, R–2000 Code.

When a disturbance signal is applied to the

TSOP18..SS3VA 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 TSOP18..SS3VA are:

• DC light (e.g. from tungsten bulb or sunlight),

• Continuous signal at 38kHz or at any other

frequency,

• Signals from fluorescent lamps (see figure B).

• Continuous IR signal (e.g. 1ms burst, 2ms pause)
