SUITABLE DATA FORMAT

This series is designed to suppress spurious output pulses

due to noise or disturbance signals. The devices can

distinguish data signals from noise due to differences in

frequency, burst length, and envelope duty cycle. The data

signal should be close to the device’s band-pass center

frequency (e.g. 38 kHz) and fulfill the conditions in the table

below.

When a data signal is applied to the product in the presence

of a disturbance, the sensitivity of the receiver is

automatically reduced by the AGC to insure that no spurious

pulses are present at the receiver’s output. Some examples

which are suppressed are:

• DC light (e.g. from tungsten bulbs sunlight)

• Continuous signals at any frequency

• Strongly or weakly modulated patterns from fluorescent

lamps with electronic ballasts (see Fig. 13 or Fig. 14).

• 2.4 GHz and 5 GHz Wi-Fi
