Interface - Drivers, Receivers, Transceivers

The TJA1041AT/VM518 is a robust physical layer transceiver, which is mainly used in automotive applications. This article dives deep into the application field and working principle of the TJA1041AT/VM518 physical layer transceiver.

Application Field

The TJA1041AT/VM518 is mainly used in automotive networks, such as the in-vehicle communication networks. This transceiver is specifically designed for twisted-pair communication systems in automotive applications, such as CAN networks and LIN networks. It is able to deliver data speeds up to 500Kbps for CAN networks and 20Kbps for LIN networks. In addition, this physical layer transceiver also supports multiple protocols, such as ISO 11898-3, ISO11898-5 and ISO11898-6, making it a great choice for automotive networks.

Working Principle

The TJA1041AT/VM518 physical layer transceiver works on the physical layer of the OSI model. At this layer, the data is transferred in a form of bits and the job of transceiver is to convert the bits into electrical signals that can be transmitted over the physical media. The transceiver is installed between the data link layer and physical layer of the system and it consists of two parts, one is the driver unit and other is a receiver unit. The driver unit is responsible for generating a differential signal that can be transmitted over the media while the receiver unit is responsible for receiving the signal.

At the transmitter side the data which comes from the data link layer is converted into differential signal by the driver unit. Then the differential signal is transmitted over the media. The signal travels through the media and then reaches to the receiver unit. The receiver unit then converts the signal back into digital form and sends it to the data link layer.

Thus, the job of the TJA1041AT/VM518 physical layer transceiver is to convert the digital signals into electrical signals and back so that the data can be transmitted over physical media. The transceiver is highly reliable and is designed to handle harsh environments, allowing automotive applications to have reliable data transmission.

Conclusion

The TJA1041AT/VM518 is a robust physical layer transceiver mainly used in automotive networks. It supports data transmission up to 500Kbps and multiple protocols, making it a great choice for automotive applications. The working principle of this physical layer transceiver is to convert the digital signal into electrical signal and vice versa to be transmitted over the physical media.
