5 / 12 page TSOP753..W, TSOP755..W www.vishay.com Vishay Semiconductors Rev. 1.5, 22-Jul-16 5 Document Number: 82497 THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE. THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 SUITABLE DATA FORMAT The TSOP753..W, TSOP755..W 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 TSOP753..W, TSOP755..W 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 pattern from fluorescent lamps with electronic ballasts (see Fig. 14 or Fig. 15) Fig. 14 - IR Disturbance from Fluorescent Lamp with Low Modulation Fig. 15 - IR Disturbance from Fluorescent Lamp with High Modulation Note • For data formats with long bursts please see the datasheet for TSOP752..W, TSOP754..W. 010 15 20 Time (ms) 16920 5 010 15 20 Time (ms) 16921 5 TSOP753..W TSOP755..W Minimum burst length 6 cycles/burst 6 cycles/burst After each burst of length a minimum gap time is required of 6 to 35 cycles ≥ 10 cycles 6 to 24 cycles ≥ 10 cycles For bursts greater than a minimum gap time in the data stream is needed of 35 cycles > 4 x burst length 24 cycles > 25 ms Maximum number of continuous short bursts/second 2000 2000 MCIR code Preferred Yes RCMM code Preferred Yes XMP-1, XMP-2, code Preferred Yes Suppression of interference from fluorescent lamps Mild and complex disturbance patterns are suppressed (example: signal pattern of Fig. 14 and Fig. 15) Critical disturbance patterns are suppressed, e.g. highly dimmed LCDs |
