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 TSOP18238 TSOP18238 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) IR Signal SUITABLE DATA FORMAT IR Signal from Fluorescent Lamp with Low Modulation 0 5 10 15 20 Time (ms) 16920 Fig. 15 - IR Signal from Fluorescent Lamp with Low Modulation · Continuous signals at any frequency · Strongly or weakly modulated noise from fluorescent lamps with electronic ballasts (see figure 15 or figure 16) IR Signal IR Signal from Fluorescent Lamp with High Modulation 0 16921 5 10 15 20 Time (ms) Fig. 16 - IR Signal from Fluorescent Lamp with High Modulation TSOP18238 TSOP18238 Minimum burst length 10 cycles/burst After each burst of length a minimum gap time is required of 10 to 70 cycles 12 cycles For bursts greater than a minimum gap time in the data stream is needed of 70 cycles > 4 x burst length Maximum number of continuous short bursts/second 800 Recommended for NEC code Yes Recommended for Mitsubishi code (38 kHz, preburst 8 ms, 16 bit) Yes Recommended for Sharp code Yes Suppression of interference from fluorescent lamps Most common disturbance signals are suppressed Note For data formats with short bursts please see the datasheet of TSOP581 TSOP581., TSOP583 TSOP583. .
