3.3 The Isolated CAN Drivers
Each CAN transceiver is isolated from the CAN controller and all other CAN transceivers. The
CAN transceiver will get the necessary power from the PCI bus via an isolated DC/DC
convert. The isolation between the CAN controller and the CAN transceiver has a delay of
maximum 50 ns in each direction. This will reduce the possible cable length with 20 meter
compared to having no isolation.
