The TSOP37540HTT1 is a remote receiver in the optical sensor category, a subset within the photo detectors expanding field of applications – detecting, measuring and processing the photo energy signals of light as reflected from its surrounding environment. Limited by a few parameters, this is made possible through the working principles of the unit.

The Working Principle

The TSOP37540HTT1 remote receiver operates by the heterodyne principle. This is based on the use of two similar frequencies: firstly, the signal frequency coming in from an external source, for instance; television remote control and the second frequency derived from the internal oscillator within the unit. The unit is internally composed by an oscillator and a limiter stage, the oscillation amplitude of which is precisely limited to the voltage threshold. When the signal frequency of an external source meets the oscillation frequency of the unit, the oscillator output is averted, which then actuates the output stage and transmits the signal.

Application Field

The TSOP37540HTT1 remote receiver proves advantageous for numerous applications. The advantages of the unit are based on its wide range for distance and frequency. It operates within the range of 30 kHz–450 kHz frequencies and with a range up to 60-meter transmitter. With this amount of power and range, the unit is ideal for consumer applications such as digital video broadcasting (DVB-H and DVB-T), camera control, RTD audio control as well as TV remote control.

The advantages of the unit minimize the time to market for numerous consumer appliances, as that of DVR receivers, multimedia players, set-top boxes, DVD players and other consumer equipment. Moreover, the unit’s small size and convenient design allows for lower energy consumption, superior reception performance in noisy environments and improved range, making it a perfect choice for a variety of consumer electronics.

Conclusion

The TSOP37540HTT1 remote receiver by virtue of its low power consumption, effective range and small sizeis perfect for consumer applications. The unit’s heterodyne principle of operation enhances its range and reception performance while offering an effective temperature range indoors and outdoors. With all these features, it is indisputably one of the best options to be considered when it comes to remote receivers.
