The Institute of Electrical and Electronics Engineers (IEEE) 1588 Precision Time Protocol (PTP) offers a way to synchronize the time between different nodes on an Ethernet network. Typically, IEEE 1588 PTP clock-synchronization accuracy is significantly less than 10µs, making it suitable for applications ranging from factory automation to telecommunications. For instance, in factory automation this protocol can synchronize sensors to control time-based assembly processes that require improved link times or low latency. There are several different ways to implement IEEE 1588 PTP, however, and in this post, we will discuss some different options.
When SFD is a critical component of your system, choose the DP83822, TI’s newest 10/100Mbps PHY with IEEE 1588 SFD. If every picosecond of accuracy counts, the DP83640 supports integrated 1588v2 hardware time stamping.
