Abstract


In the interior of the car , there are a lot of electronic equipment , and they need a lot of wires to achieve interconnection and communication . These wires are not only occupy most of the space in the car , but also seriously affect the security of the car . In order to solve this problem , the German bosch developed a serial communication bus - CAN bus to solve the communication problems of these electronic devices . Through continuous development , CAN has become one of the most widely used international fieldbus . CAN bus transceiver design and research . CAN transceiver between the protocol controller and the physical bus interface for the bus , it can provide a different transmission performance, while the protocol controller to provide different reception performance . The chip has the following characteristics : Fully compliant with ISO11898 standard ; input stage is compatible with 3.3V and 5V devices ; unpowered node does not cause disturbance to the bus ; provides a high - speed mode and silent mode both work ; output driver stage by temperature protection ; transmit data (TXD) controls the time-out function ; ; least 110 nodes can be connected to the power and ground short-circuit proof . This paper first introduces the basic knowledge of the research background , research directions , and CAN transceiver , and then introduces the overall framework and the external topology of the chip . On this basis , the details submodule chip design as well as the corresponding simulation and chip layout design , the main work of this paper concluded .
