Infrared Data Association (IrDA) transceiver modules enable short-range inter-electronic communication using infrared light, and the ZHX1820TV115XHTR is a widely used multi-voltage device from ZHX Corporation offering exceptional performance for a variety of applications. This article details the design and operation of the ZHX1820TV115XHTR transceiver module and the potential applications and use scenarios it offers.

Overview of ZHX1820TV115XHTR

ZHX Corporation’s ZHX1820TV115XHTR is a multi-voltage IrDA transceiver module designed specifically for applications that require reliable, low power, fast data communication solutions. The module operates in the 850-950nm sprectrum, with an optical power output up to 5mW and a data rate of up to 27 Mbps. It is designed to meet the standards of the IrDA-compliant devices, which allows flexible compatibility and operation with a wide variety of representative equipment. The ZHX1820TV115XHTR is not only proven to reduce electromagnetic interference (EMI) through integrated shielding, but also is highly reliable and precision-tooled for accuracy and to reduce data transmission errors.

Design and Operation of ZHX1820TV115XHTR

The ZHX1820TV115XHTR transceiver module is based on a simple design and utilizes a zinc oxide LED for emission and a photodiode for reception. The zinc oxide LED outputs a modulated infrared signal at 850-950 nm using an oscillator frequency up to 940 kHz with an input current of 20mA. The signal is emitted in an elliptical pattern, allowing for a larger transmission range and greater power efficiency than comparable devices. The LED construction is also overmolded in soft rubber to protect the sensitive components, further improving the device’s durability and reliability. At the receiving end, the voltage of the transceiver’s photodiode indicates the received signal strength, which is adjustable and calibrated for a wide range of compatibility.

The ZHX1820TV115XHTR is configurable to operate in either full-duplex or half-duplex configuration, making it suitable for a wide variety of applications. It communicates in both directions simultaneously or allows for one-way data transmission. The module is also equipped with an auto-acknowledgement mechanism, allowing the receiver to automatically respond to transmitted data.

Application Field and Working Principle

The ZHX1820TV115XHTR transceiver module is suitable for a variety of applications such as infrared data exchange between integrated circuits (ICs), remote control of consumer electronic devices, wireless keyboards and mice, and automotive applications. Its exceptional performance and flexibility make it a top contender for the aforementioned applications.

The basic working principle of the ZHX1820TV115XHTR transceiver module is simple. The device utilizes a zinc oxide LED for emission and a photodiode for reception. When the transceiver receives an infrared signal, it is detected by the photodiode and sent to the output. The receiver then responds with an acknowledgement signal to indicate that the received signal has been processed. This process is repeated throughout the communication between two devices.

Conclusion

The ZHX1820TV115XHTR transceiver module is a highly reliable device capable of delivering both high-speed and low-power solutions in multiple applications. For any application requiring short-range wireless communication using infrared light, the ZHX1820TV115XHTR is a powerful and efficient choice.
