Recommendation for Suitable Data Formats

The circuit of the TSOP5700 is designed in that way that disturbance signals are identified and unwated output pulses due to noise or disturbances are avoided. A bandpass filter, an automatic gain control and an integrator stage is used to suppress such disturbances. The distinguishing marks between data signal and disturbance are carrier frequency, burst length and the envelope duty cycle.

The data signal should fulfill the following conditions:

• The carrier frequency should be close to 455 kHz.

• The burstlength should be at least 22 µs (10 cycles of the carrier signal) and shorter than 500 µs.

• The separation time between two consecutive bursts should be at least 26 µs.

• If the data bursts are longer than 500 µs then the envelope duty cycle is limited to 25 %

• The duty cycle of the carrier signal (455 kHz) may be between 50 % (1.1 µs pulses) and 10 % (0.2 µs pulses). The lower duty cycle may help to save battery power.
