HSDL-3602-038

Infrared Data Association (IrDA) transceiver modules have become essential components for a wide range of portable and embedded device applications. Specifically, the HSDL-3602-038 transceiver module is a high performance infrared communications product from Avago Technologies used in consumer products, such as cellular phones, PDAs, digital cameras, and more. It is designed to be an energy-efficient and cost-effective solution to achieve reliable one-way or two-way data transmission.

Application field

Avago\'s HSDL-3602-038 is designed to provide reliable and high-speed infrared communication in a variety of applications. It is an ideal solution for data transmission between laptop to laptop, notebook to peripherals, personal digital assistant (PDA) to PDA, digital camera to PDA, digital camera to computer, and many other combinations. This low-cost and low-power design allows for applications such as cable-free home networking, hard disk backup, wireless gaming, and many more.

Working Principle

IrDA transceiver module HSDL-3602-038 from Avago Technologies is a high performance solution for short distance infrared data exchange. It utilizes infrared light to provide a point-to-point data transmission link between two devices. The data is transmitted in a half duplex manner, and the module supports standard data rates from 192 Kb/s to 4 Mb/s. The module is designed for low-power consumption and is ideal for battery-powered applications.

The module consists of two parts, an integrated transceiver and a separate push-to-talk (PTT) module. The transceiver consists of an infrared emitting diode (IRED) and an infrared phototransistor. Together, they form the basis for the two-way communication that is needed to achieve the point-to-point link. The transceiver is designed for peak performance in the near-infrared (NIR) spectral band (850nm to 950nm).

The PTT module is a second component of the design. It consists of a miniature infrared signal detector that senses infrared light emission from the IRED to enable the transmission of data. This module ensures that data is sent only when the other device is receiving and eliminates the need for a direct radio frequency (RF) connection between the two devices.

Conclusion

Avago\'s HSDL-3602-038 is a reliable and cost-effective infrared data transceiver module designed for short-distance, two-way data exchange. This low power, low cost design is ideally suited for battery-powered applications, such as consumer electronics, home networking, and hard disk backup/wireless gaming. The module consists of an integrated transceiver and a separately available PTT module that enable half duplex communication between two devices.
