ei813 分布时钟—从器件和主器件上的时间同步方法。

支持环回的快速链路断开检测（需要以太网物理层 (PHY) 收发器支持）--当以太网PHY检测到一个链路断开时，它通知EtherCAT硬件。在10µs内，EtherCAT硬件将环回EtherCAT数据帧。请查看TI的TLK1xx以太网PHY收发器系列，这个系列的器件支持快速链路断开特性。

在EtherCAT中使用ASIC或FPGA会增加成本和电路板面积。一个替代的解决方案就是使用许多TI Sitara处理器中的PRU-ICSS外设。例如，TI提供针对AM335x处理器的PRU-ICSS固件，从而使EtherCAT从器件无需使用一个外部FPGA（图3）。你可以用TMDSICE3359评估板来评估TI的EtherCAT从器件解决方案。
