Controller Area Network (CAN Bus) - Bit Timing And Synchronization

First check the possible configurations given the desired data rate and the CAN-controller clock. The TQ interval must be calculated based on the clock and various BRP values, and only the combinations where the TQ interval divides into the bit time by an integer number are possible. Depending on the … See more Controller area network (CAN) offers robust communication between multiple network locations, supporting a variety of data rates and distances. Featuring data-link layer arbitration, synchronization, and error handling, CAN … See more For harsh industrial and automotive environments, system robustness can be further enhanced by isolating the logic interface to the CAN transceiver, allowing large potential … See more With isolation, an extra element must be considered in the round trip propagation delay calculation. Digital isolators reduce the propagation delay compared to optocouplers, but even the fastest isolated CAN transceivers will … See more Implementing a CAN node requires an isolated or nonisolated CAN transceiver and a CAN controller or processor with the appropriate protocol stack.

WebThe CAN protocol has defined a recessive (logic ‘1’) and dominant (logic ‘0’) state to implement a non-destructive bit-wise arbitration scheme. It is this arbitra-tion methodology that is affected most by propagation delays. Each node involved with arbitration must be able to sample each bit level within the same bit time.
