Application Circuit
Recommendation for Suitable Data Formats
The circuit of the TSOP7000 is designed in that way that disturbance signals are identified and unwated output
pulses due to noise or disturbances are avoided. A bandpassfilter, 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 fullfill the following conditions:

*) tolerated supply voltage range: 2.7V < V
The carrier frequency should be close to 455kHz.
The burstlength should be at least 22
The separation time between two consecutive bursts should be at least 26
If the data bursts are longer than 500
The duty cycle of the carrier signal (455kHz) may be between 50% (1.1
The longer duty cycle may help to save battery power.
With the resistor R1 the slopes of the output pulse are becoming faster.
