2.1
The CAN transceiver IFX1054G works as the interface between the CAN protocol controller and the physical CAN
bus-lines.
The IFX1054G is optimized for low-speed data transmission (up to 125 kBaud) in industrial applications.
In Normal operation mode a differential signal is transmitted / received. When bus wiring failures are detected the
device automatically switches in a dedicated single-wire mode to maintain communication.
While no data is transferred, the power consumption can be minimized by multiple low power operation modes.
Further a Receive - Only mode is implemented.
To reduce radiated electromagnetic emission (EME) the dynamic slopes of the CANL and CANH signals are both
limited and symmetric. This allows the use of an unshielded twisted or parallel pair of wires for the bus. During
single-wire transmission (one of the bus lines is affected by a bus line failure) the EME performance of the system
is degraded from the differential mode.
In case the transmission data input TxD is permanently dominant, both, the CANH and CANL transmitting stage
are disabled after a certain delay time. This is necessary to prevent the bus from being blocked by a defective
protocol unit or short to GND at the TxD input.
