1. DESCRIPTION

The TSOP22.., TSOP48.., TSOP2438 and TSOP44.. series are miniaturized IR receiver modules for infrared remote control systems. A PIN diode and a preamplifier are assembled on lead frame, the epoxy package contains an IR filter. The demodulated output signal can be directly connected to a microprocessor for decoding. The TSOP2438, TSOP44.. series devices are optimized to suppress almost all spurious pulses from Wi-Fi and CFL sources. They may suppress some data signals if continuously transmitted. The TSOP22.., TSOP48.. series devices are provided primarily for compatibility with old AGC2 designs. New designs should prefer the TSOP2438, TSOP44.. series containing the newer AGC4. These components have not been qualified according to automotive specifications.

5. Appropriate data format

This series is designed to suppress false output pulses Due to noise or interference signals. These devices can Distinguish between data signal and noise due to differences Frequency, burst length and envelope duty cycle. data The signal should be close to the bandpass center of the device Frequency (e.g. 38 kHz) and meets the conditions in the table the following. When the data signal is applied to the product The presence of interference, the sensitivity of the receiver Automatically reduced by AGC to ensure that there is no There are stray pulses at the output of the receiver. Some Examples of being suppressed are:

    1. DC light (such as sunlight from a tungsten bulb)

    2. Continuous signal of any frequency

    3. Strong or weak modulation mode from fluorescence Lamps with electronic ballasts (see Figure 13 or Figure 14).

    4. 2.4 GHz and 5 GHz Wi-Fi
