5 / 8 page www.vishay.com Document Number: 81222 174 Rev. 1.3, 18-Jul-08 New TSOP592.. Vishay Semiconductors IR Receiver Modules for Remote Control Systems SUITABLE DATA FORMAT The TSOP592.. series is 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 TSOP592.. 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 • Strongly or weakly modulated noise from fluorescent lamps with electronic ballasts (see figure 15 or figure 16) Fig. 15 - IR Signal from Fluorescent Lamp with Low Modulation Fig. 16 - IR Signal from Fluorescent Lamp with High Modulation Note For data formats with short bursts please see the data sheet of TSOP591.. 010 15 20 Time (ms) 16920 IR Signal from Fluorescent Lamp with Low Modulation 5 010 15 20 Time (ms) 16921 IR Signal from Fluorescent Lamp with High Modulation 10 TSOP592.. 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 Compatible to NEC code yes Compatible to RC5/RC6 code yes Compatible to Sony code yes Compatible to Thomson 56 kHz code yes Compatible to Mitsubishi code (38 kHz, preburst 8 ms, 16 bit) yes Compatible to Sharp code yes Suppression of interference from fluorescent lamps Most common disturbance signals are suppressed |
