How do I calculate how many nodes, how fast I can use, and how far can I connect the MAX3053?
A:The ISO 11898 formally defines the maximum number of nodes to be 30. However, you can have more nodes if high-quality cabling, CAN repeaters, and strict voltage supply regulation is used..
The maximum bus length has its trade-offs with signaling rate. The major factor that limits the signaling rate is the cable bandwidth. The maximum signaling rate is determined from the total delay of the CAN network which includes:
- The distance between the two farthest nodes.
- Propagation delay going in and out of the nodes.
- Insertion loss of the signal due to cable length.
