定义
A CAN Transceiver Interface is an electronic component that converts digital signals from a CAN controller into differential voltage signals for transmission over the CAN bus, and vice versa for reception. It provides electrical isolation, noise immunity, and signal conditioning to ensure reliable data exchange in harsh industrial environments with electromagnetic interference.
工作原理
The CAN Transceiver Interface operates by receiving digital data from the CAN controller, converting it into differential voltage signals (CAN_H and CAN_L) for transmission on the bus. During reception, it detects differential voltage levels on the bus, converts them back to digital signals, and provides them to the CAN controller. It includes features like bus fault protection, thermal shutdown, and common-mode rejection to maintain communication integrity.
