The TJA1049T type 118 transceiver uses a physical layer interface based on the CAN (Controller Area Network) protocol. The transceiver consists of two units, which are the CAN controller and transceiver.The CAN controller is responsible for managing the data transfer between the CAN bus and the transceiver. It also provides the necessary control signals to the transceiver. The CAN controller is capable of operating at speeds up to 125 Kbps, depending on the application.The transceiver is responsible for providing electrical isolation between the two parts of the CAN interface. It also provides data rate conversion between the high-speed CAN bus and the low-speed bus of the microcontroller.The transceiver includes many internal blocks, such as the receive and transmit filters, data rate converters, local oscillators, and the bus interface. All of these internal blocks enable the transceiver to operate at speeds of up to 120 Kbps and meet the necessary levels of noise immunity.Conclusion
The TJA1049T Type 118 is a physical layer transceiver designed for use in Interface – Drivers, Receivers, Transceivers applications. It has a number of features, including a high-speed data rate, high-output power, low-power consumption, and advanced detection capabilities. This transceiver is perfectly suited for a variety of applications, including industrial control systems, automotive communication networks, consumer electronics, robotics, and medical devices. The transceiver is based on a CAN (Controller Area Network) protocol and is capable of operating at speeds of up to 120Kbps.
