so-called dominant signal level on the bus lines (see Figure 2.3). The output driver CANH provides a
source output from V
and the output driver CANL a sink output towards GND. As an example Figure
2.2 shows the block diagram of the TJA1050.
The bus is in recessive state if no bus node transmits a dominant bit. If one or multiple bus nodes transmit
a dominant bit, the bus lines enter the dominant state thus overriding the recessive state (wired-AND
characteristic).
The receiver comparator converts the differential bus signal to a logic level signal, which is output at RxD.
The serial receive data stream is provided to the bus protocol controller for decoding. The receiver
comparator is always active i.e. it monitors the bus while the bus node is transmitting a message. This is
required to support the non-destructive bit by bit arbitration scheme of CAN.
Typically the bus is set up with a pair of twisted wires. Considering a linear topology specified in
ISO11898 the two bus ends are terminated with a resistor of nominal 120
. This results in the required
bus load of nominal 60
. Close matching of the termination resistor with the cable impedance ensures
that data signals will not be reflected at the bus ends.
