Description

The TSOP11..RF1 ± 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 operation with short burst transmission codes (e.g. RECS 80) and high data rates.

TSOP11..RF1

Suitable Data Format

The circuit of the TSOP11..RF1 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 TSOP11..RF1 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..RF1 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).
