2.3 Key IEEE 1588 Features  
IEEE 1588 provides a time synchronization protocol, often referred to as the Precision Time Protocol  
(PTP), which synchronizes time across an Ethernet network. DP83640 supports IEEE 1588 Real Time  
Ethernet applications by providing hardware support for three time critical elements.  
IEEE 1588 synchronized clock generation  
Packet timestamps for clock synchronization  
Event triggering and timestamping through GPIO  
By combining the above capabilities, the DP83640 provides advanced and flexible support for IEEE 1588  
for use in a highly accurate IEEE 1588 system.  
The DP83640 provides features for controlling the clock operation in Slave mode. The clock value can be  
updated to match the Master clock in several ways. In addition, the clock can be programmed to adjust its  
frequency to compensate for drift.  
The DP83640 supports real time triggering activities and captures real time events to report to the  
microcontroller. Controlled devices can be connected to the DP83640 through the available GPIO.  
The IEEE 1588 features are briefly presented below. For a more detailed discussion on configuring  
the IEEE 1588 features, refer to the Software Development Guide for the DP83640.
