TJA1083TT FlexRay node transceiver

The TJA1083 FlexRay node transceiver is compliant with the FlexRay Electrical Physical Layer specification V3.0.1. In order to meet JASPAR the equirements, it implements the ‘Increased voltage amplitude transmitter’ functional class. It is primarily intended for communication systems operating at between 2.5 Mbit/s and 10 Mbit/s, and provides an advanced interface between the protocol controller and the physical bus in a FlexRay network. The TJA1083 offers an optimized solution for Electronic Control Unit (ECU) applications that do not need enhanced power management and are typically switched by the ignition or activated by a dedicated wake-up line.

The TJA1083 provides a differential transmit capability to the network and a differential receive capability to the FlexRay controller. It offers excellent ElectroMagnetic Compatibility (EMC) performance as well as high ElectroStatic Discharge (ESD) protection.

The TJA1083 actively monitors system performance using dedicated error and status information (readable by any microcontroller), as well as internal voltage and temperature monitoring
