IR Receiver Modules for Remote Control Systems Vishay Semiconductors The TSOP322.., TSOP324.. series 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 TSOP322.., TSOP324.. 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: IR Signal SUITABLE DATA FORMAT IR Signal from Fluorescent Lamp with Low Modulation * DC light (e.g. from tungsten bulb or sunlight) * Continuous signals at any frequency 5 0 10 15 20 Time (ms) 16920 Fig. 14 - IR Signal from Fluorescent Lamp with Low Modulation * Strongly or weakly modulated noise from fluorescent lamps with electronic ballasts (see figure 14 or figure 15) IR Signal IR Signal from Fluorescent Lamp with High Modulation 10 0 10 15 20 Time (ms) 16921 Fig. 15 - IR Signal from Fluorescent Lamp with High Modulation TSOP322..
