This table describes the minimum programmable ranges required by the CAN protocol
A given bit rate may be met by different bit time configurations, but for the proper function of the
CAN network the physical delay times and the oscillator’s tolerance range have to be considered.
This part of the bit time is used to compensate physical delay times within the network. These
delay times consist of the signal propagation time on the bus and the internal delay time of the
CAN nodes.
Any CAN node synchronized to the bit stream on the CAN bus will be out of phase with the
transmitter of that bit stream, caused by the signal propagation time between the two nodes. The
CAN protocol’s non-destructive bitwise arbitration and the dominant acknowledge bit provided by
receivers of CAN messages requires that a CAN node transmitting a bit stream must also be able
to receive dominant bits transmitted by other CAN nodes that are synchronized to that bit stream.
The example in Figure 5-84 shows the phase shift and propagation times between two CAN
nodes.
