TJA1083G device offers an optimized solution for Electronic Control Unit applications that do not need enhanced power management as FlexRay node transceiver. It is compliant with the FlexRay Electrical Physical Layer specification ISO 17458-4:2013.

TJA1083G FlexRay™ node transceiver is primarily intended for communications 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.

Why Used

  • Low-power management
    • Very low current consumption in Standby mode
    • Remote wake-up via a wake-up pattern or dedicated FlexRay data frames on the bus lines
  • Optimized for time-triggered communication systems
    • Compliant with ISO 17458-4:2013 (see Ref. 2)
    • Automotive product qualification in accordance with AEC-Q100
    • Data transfer rates from 2.5 Mbit/s to 10 Mbit/s
    • Supports 60 ns minimum bit time at 400 mV differential input voltage
    • Very low ElectroMagnetic Emission (EME) to support unshielded cable, meeting the latest industry standards
    • Differential receiver with high common-mode range for excellent ElectroMagnetic Immunity (EMI), meeting the latest industry standards
    • Auto I/O level adaptation to host controller supply voltage VIO
    • Can be used in 14 V, 24 V and 48 V powered systems
    • Instant transmitter shut-down interface (BGE pin)
