Shown here is a subsystem block diagram showing a multidrop CAN bus network. Each transceiver connects to a local CAN controller or a microcontroller. The network is terminated at each end with 120 Ω termination resistors to reduce line reflections. In this example, the termination is implemented with a split approach, two 60 Ω resistors split by a 47nF capacitor. Standby, normal, and slow slew rate modes are controlled by the microcontroller or CAN controller at each node.
