HSDL-3200#021 IrDA Transceiver Modules

The HSDL-3200#021 is an Infrared Data Association (IrDA) transceiver module developed with the purpose of providing a reliable and low power design solution for IrDA wireless communications. It is optimized for speeds up to 115.2Kbps in full-duplex mode and has a versatile and modular design that allows it to be customized to suit specific applications.

The HSDL-3200#021 consists of a transmitter and receiver, a SNAC (Serial Network Access Controller) as well as a control unit. The transmitter employs an anti-collision algorithm to ensure reliable data transmission. The receiver uses an Advanced Data Rate (ADR) feature to maximize reliability.

The SNAC is designed to provide a high level of data transfer integrity and reliability. It is also responsible for handling the handshaking between two device, error detection, and framing. The control unit includes a suite of interrupts, software-controlled I/O, and overall system control.

In terms of the physical characteristics of the module, the HSDL-3200#021 has a high robustness to shock and vibration and also an inherent immunity to electromagnetic interference. In terms of power consumption, the module has a low active mode power consumption of 140 mW at 3.3 V. It also features a low standby current of 1.7 mA and a power-down current of 20 µA. The overall dimensions are 95 x 16 x 7 mm.

The HSDL-3200#021 is designed for use in applications such as instrumentation, portable devices, healthcare, medical, automotive, consumer electronics, and industrial and safety applications. It is also ideal for wireless device-to-device communication and is suitable for communication between PCs, PDAs, printers, and other electronic devices.

Working Principle

The working principle of the HSDL-3200#021 is based on Infrared Data Association (IrDA) protocol which is designed to allow data to be exchanged between two devices located close together. The module transmits using modulated pulse infrared radiation, and the receiving device senses this radiation and reconstructs the data.

The HSDL-3200#021 consists of an infrared light emitting diode (LED) which is connected to the Tx pin and a photodiode (PD) which is connected to the Rx pin. When data is transmitted the Tx LED transmits an infrared pulse which is modulated by the transmitted data. This pulse is received by the PD of the receiving device. The data is then extracted from the received pulsed signal using demodulation techniques.

The module also contains a Serial Network Access Controller (SNAC) which is responsible for the handshaking and error control of the module. The SNAC ensures that the data is transmitted reliably and without errors. The SNAC also provides a high level of safety in transmission and reception and is designed to ensure that both the transmitting and receiving devices receive the same amount of data.

Conclusion

The HSDL-3200#021 is an IrDA transceiver module optimized for speeds up to 115.2Kbps in full-duplex mode and is designed for use in a variety of applications. It has a high robustness to shock and vibration and also an inherent immunity to electromagnetic interference. In addition, it has a low active mode power consumption and a low standby current. The working principle of the module is based on the Infrared Data Association protocol which is designed specifically for wireless device-to-device communication.
