SUITABLE DATA FORMAT
These products are designed to suppress spurious output
pulses due to noise or disturbance signals. Data and
disturbance signals can be distinguished by the devices
according to carrier frequency, burst length and envelope
duty cycle. The data signal should be close to the
band-pass center frequency (e.g. 38 kHz) and fulfill the
conditions in the table below.
When a data signal is applied to the IR receiver in the
presence of a disturbance signal, the sensitivity of the
receiver is reduced to insure that no spurious pulses are
present at the output. Some examples of disturbance
signals which are suppressed are:
DC light (e.g. from tungsten bulb or sunlight)
Continuous signals at any frequency
Modulated noise from fluorescent lamps with electronic
ballasts (see figure 14 or figure 15)
Fig. 13 - IR Signal from Fluorescent Lamp
with Low Modulation
Fig. 14 - IR Signal from Fluorescent Lamp
with High Modulation
Note
For data formats with long bursts (more than 10 carrier cycles) please see the datasheet for TSOP348.., TSOP344.., TSOP322.., TSOP324..
