    User Guide Introduction Although IEEE 1588 Precision Time Protocol (PTP) support has been part of Intel's controller product line for generations. Intel only recently began developing PTP-optimized Ethernet Network Adapter products. The adoption of PTP in Ethernet connections is growing rapidly. Although the leader use case being considered is the build-out of 5G infrastructure, other applications that exist in datacenters, point of presence, financial, industrial, and energy sectors.

    • Driver support for Linux PTP stack (ptp4l) to send synchronization messages and synchronize the host system clock to the adapter's PHC. This is present in all Intel network adapters. • Newly-developed utility (ts2phc) for the Linux PTP stack optimized for synchronizing the PHC to a 1PPS input, rather than PTP messages.
