Photo Modules for PCM Remote Control Systems

Available types for different carrier frequencies

Type	fo	Type	fo
TSOP4130	30 kHz	TSOP4133	33 kHz
TSOP4136	36 kHz	TSOP4137	36.7 kHz
TSOP4138	38 kHz	TSOP4140	40 kHz

Description
The TSOP41.. ± 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.	14 500

Suitable Data Format

The circuit of the TSOP41.. 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, 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 TSOP41.. 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 TSOP41.. 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 shown in the figure below).
