TJA1083GTT/0Z

TJA1083GTT/0Z is a FlexRay node transceiver that is compliant with the FlexRay electrical physical layer specification ISO 17458-4:2013. It is primarily intended for communication systems operating at between 2.5Mbit/s and 10Mbit/s, and provides an advanced interface between the protocol controller and the physical bus in a FlexRay network. The TJA1083G 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. It provides a differential transmit capability to the network and a differential receive capability to the FlexRay controller. It offers excellent Electro Magnetic Compatibility (EMC) performance as well as high ElectroStatic Discharge (ESD) protection. It actively monitors system performance using dedicated error and status information (readable via SPI), as well as internal voltage and temperature monitoring.
