TJA1041T/N,112 is an automotive Ethernet transceiver which enables the implementation of Ethernet in an automotive environment. It is a highly integrated device with high level of integration that combines the physical, data link and network layers in a single device.

The TJA1041T/N,112 is an interface device that acts as a bridge between the Ethernet and automotive networks. It is used as a bridge between the Ethernet traffic and the Automotive Local Area Network (ALAN) traffic, providing communication and control information from one to the other. It enables the connection to the CAN, LIN, and MOST networks, which are used for vehicle communications purposes. Additionally, the transceiver can be used for the transmission of time-triggered protocols and point-to-point protocol data frames, making it a highly reliable and secure data link.

The TJA1041T/N,112 is suitable for automotive systems, including collision avoidance systems, entertainment systems and infotainment, advanced driver assistance systems (ADAS) and telematics. It supports communication in automotive buses, including CAN, LIN and MOST. The transceiver’s two channels operate at data rates up to 10 Mbps and feature a programmable wake-up feature that enables communication only when necessary, making the transceiver power efficient.

The application field and working principle of the TJA1041T/N,112 is to facilitate and control communication between Ethernet devices and automotive networks, allowing for rapid data transfer. The transceiver has two channels, each with its own digital input, block check character (BCC) generator, driver and receiver. The transceiver uses an analog monitoring scheme to detect data transmission and to automatically switch channels and adjust supply voltage for good reception. The channel selection process is done by software, through MCU with optional communication interface.
