FlexRay™ Node Transceiver - Clamp 15
The TJA1083G FlexRay™ node transceiver is compliant with the FlexRay Electrical Physical Layer specification ISO 17458-4:2013. The TJA1083G is a Clamp 15 transceiver, optimized for applications that are switched off by the ignition key. 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.
- Offers an optimized solution for electronic control unit applications that are not directly connected to the battery and are switched on and off by the ignition key.
- 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.

- 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)
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
Diagnosis and Robustness
- Enhanced supply voltage monitoring for VCC and VIO
-
Two error diagnosis modes:
- Status register readout via the Serial Peripheral Interface (SPI)
- Simple error indication via pin ERRN
- Overtemperature detection
- Short-circuit detection on bus lines
- Power-on flag
- Clamping diagnosis for pins TXEN and BGE
- Bus pins protected against ±6 kV ESD pulses according to IEC61000-4-2 and ±8 kV according to HBM
- Bus pins protected against transients in automotive environment (according to ISO 7637 class C)
- Bus pins short-circuit proof to battery voltage (14 V, 24 V and 48 V) and ground
- Maximum differential voltage between pins BP or BM and any other pin of 60 V
- Bus lines remain passive when the transceiver is not powered
- No reverse currents from the digital input pins to VIO or VCC when the transceiver is not powered
Functional classes According to FlexRay Electrical Physical Layer Specification V3.0.1
- Bus driver - bus guardian control interface
- Bus driver - logic level adaptation
- Bus driver - remote wake-up
