5.1. Precision Time Protocol

The Precision Time Protocol (PTP) provides 1588 Precision Time Protocol timestamp information as defined in the IEEE 1588-2008 Precision Clock Synchronization Protocol for Networked Measurement and Control System Standard. 1588 PTP logic generates 96-bit timestamp information for transmitted and received packets. The generated timestamps represent the time when the first bit after the Start of Frame Delimiter (SFD) byte crosses the FPGA serial pins (Medium Dependent Interface, MDI).

The detailed implementation, including the IP and PTP tile adapter connections and the PTP client flow, is described in the F-Tile Ethernet Intel® FPGA Hard IP User Guide.
