Applications

The TLK106LRHBR transceiver is ideal for data acquisition and transmission applications. Its small footprint makes it suitable for use in a variety of embedded applications such as medical devices and wearable devices. The device is also suitable for robotic vision, industrial automation, and consumer electronics.

Working Principle

The TLK106LRHBR is designed to transfer data using two separate communication channels: an LED channel and a data cable channel. The LED channel utilizes a high-power LED to transmit data, while the data cable channel uses two twisted-pair cables to transmit data. Both channels use Manchester coding to ensure that data is transmitted reliably without errors.

The device is designed to interface with up to four-wire communication protocols, allowing for both differential and single-ended data transmission. Differential mode uses two twisted-pair cables for data transmission, while single-ended mode only uses one cable for data transmission. The device is capable of data rates up to 136 Mbps in single-ended mode and 2 Mb/s in differential mode.

The integrated LED source is powered with a DC voltage, while the integrated photodiode is an AC-coupled device. The photodiode is connected between two nodes, and the output is connected to the base of a transistor, allowing the transceiver to be used as a receiver. The output of the receiver is then sent to a logic circuit, which is used to decode the received data.

Conclusion

The TLK106LRHBR optical transceiver is a low-cost, bidirectional device designed for data transmission and reception. It features integrated LEDs, an integrated photodiode, and internal electronics for interfacing with up to four-wire communication protocols. It is suitable for a variety of embedded applications, including medical devices, wearable devices, robotic vision, industrial automation, and consumer electronics. The TLK106LRHBR is capable of data rates up to 136 Mbps in single-ended mode and 2 Mb/s in differential mode, making it an ideal choice for many applications.
