Application Field and Working Principle

The TJA1083GTT/0Z has proved to be an ideal physical layer transceiver for Controller Area Network (CAN). The device can be used in a variety of CAN-based networks, such as automotive networks, industrial networks and home automation networks. The main features of the TJA1083GTT/0Z make it an ideal solution for automotive applications. It provides low standby current consumption of 10μA, short wakeup time of less than 7μs, a wide data rate range of 125Kbps to 1Mbps, and in addition, a robust electro-magnetic compatibility (EMC).

In CAN networks, the TJA1083GTT/0Z serves as a physical layer transceiver that bridges the network layer and the physical layer protocols. In addition, it supports the ISO11898-2/TIA/EIA/CISPR 21 Class B requirements for automotive EMC. The device supports CAN protocols at a data rate range of 125Kbps to 1Mbps. It also provides features such as Wakeup Time of less than 7μs, Standby Current Consumption of 10μA, over-voltage protection and Over-current Protection. Furthermore, the TJA1083GTT/0Z offers thermal protection which shuts the driver down if the junction temperature exceeds the specified temperature. It also provides ESD protection up to ±15kV.

The device performs essential functions such as transmitting and receiving data, calculating checksums, error detection, framing and collision detection. In terms of data transmission and reception, the TJA1083GTT/0Z offers data rates of 125Kbps to 1Mbps. In addition, the device implements 15-Pulse Error Detection (PED) to detect both short and long errors. Furthermore, the device performs transmission control to ensure that the data is transmitted in a controlled manner. This helps to ensure that all data frames in the network are transmitted reliably and with the required timing.

The TJA1083GTT/0Z also supports both local and remote wakeup commands. The local wakeup is triggered by the internal logic and the remote wakeup command is triggered by an external controller. This feature helps to reduce power consumption by allowing the device to stay in low power mode until a wakeup condition is received. This helps to ensure that the device is active only when necessary, thus reducing power consumption.

To sum up, the TJA1083GTT/0Z is a physical layer line transceiver designed to meet the physical layer requirements of CAN as described in ISO11898-2. It is suitable for use in a variety of CAN-based networks, such as automotive networks, industrial networks and home automation networks. It provides features such as low standby current consumption of 10μA, short wakeup time of less than 7μs, and a wide data rate range of 125Kbps to 1Mbps. Furthermore, it provides electro-magnetic compatibility (EMC) and thermal protection. Additionally, it supports both local and remote wakeup commands. It performs essential functions such as transmitting and receiving data, calculating checksums, error detection, framing and collision detection. Therefore, the TJA1083GTT/0Z is an ideal physical layer transceiver for Controller Area Network applications.
