AM65xx Time Synchronization Architecture

This application report describes the multi-protocol time synchronization architecture of the AM65xx-class of devices. It starts with an overview of time-sync protocols and their applications in automation and industrial control systems. Then, introduces hardware components of the time-sync network in the device. Followed by, two example embedded systems where multi-protocol time-sync are implemented based on this architecture.
