1. General description
The TJA1083G FlexRay node transceiver is compliant with the FlexRay Electrical
Physical Layer specification ISO 17458-4:2013 (see Ref. 1 and Ref. 2). 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 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.
The TJA1083G 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)
The TJA1083G actively monitors system performance using dedicated error and status
information (readable via SPI), as well as internal voltage and temperature monitoring.
The TJA1083G is fully functionally and pin compatible with the TJA1083 (see Ref. 3).
