CAN XL
CAN进化的下一步

CAN XL通过保持CAN协议的优势(例如无损仲裁的冲突解决),为高达10Mbit / s的数据速率提供了出色的解决方案。
关于比特率,CAN XL填补了CAN FD与100BASE-T1(以太网)之间的空白。
状态

The specification of the CAN XL protocol and physical layer is done by the CiA Special Interest Group CAN XL in the CiA610 document series.
CiA CAN XL规范于2018年12月开始,目标是在2020年底之前拥有OSI第2层的技术稳定的CAN XL规范(称为CAN XL协议)。第二步,将开始进行ISO标准化。此外,还将同时更新许多其他与CAN相关的标准,以支持CAN XL。示例包括根据ISO16845和物理层的CAN一致性测试。
关键协议特征

- 净数据速率高达10Mbit/s
- 高达2048字节的大数据字段支持使用更高层的协议,例如IP(Internet协议),甚至可以传输完整的以太网帧
- 与CAN FD的互操作性,用于混合FD/XL网络
物理层

CAN XL将可用于所有收发器::
- 经典CAN高达1Mbit/s
- CAN FD高达2Mbit/s, CAN FD-SiC高达5-8Mbit/s
- CAN XL高达10 Mbit/s及以上 (待开发)
