Table 9.1 Maximum number of nodes
/CZKOWO$WU.KPG.GPIVJ
The maximum achievable bus line length in a CAN network is determined essentially by the following
physical effects:
1. The loop delays of the connected bus nodes (CAN controller, transceiver etc.) and the delay of the bus
line
2. The relative oscillator tolerance between nodes
3. The signal amplitude drop due to the series resistance of the bus cable and the input resistance of bus
nodes (for a detailed description refer to [6])
Effects 1 and 2 determine a value for the maximum bus line length with respect to the CAN bit timing
[5]. Effect 3, on the other side, determines a value with respect to the output signal drop along the bus
line. The minimum of the two values has to be taken as the actual maximum allowable bus line length. As
the signal drop is only significant for very long lengths, effect 3 can often be neglected for high data rates.

Table 9.2 Maximum bus line length for some standards and the TJA1050
Table 9.2 gives the maximum bus line length for the bit rates 500kbit/s and 250kbit/s, along with values
specified in some standards associated to CAN. The calculation is based on effects 1 and 2 assuming an
oscillator tolerance of better than 0.15%. Notice that the stated values apply only for a well terminated
linear topology. Bad signal quality because of improper termination can lower the maximum allowable bus
length.
