Description

The TSOP1 1..SB1 – 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 de-

coded 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..SB1 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

TSOP11..SB1 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..SB1 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).
