IEEE 1588 v2.1 PTP Solution
Timestamping Unit IP & Software Stack
Overview
Comcores IEEE 1588 Precision Time Protocol (PTP) Solution is a high quality and high performance time synchronization solution, including Timestamping Unit IP (TSU) and PTP Software Stack. The PTP solution is fully compliant with IEEE 1588 v2.1 and IEEE 1588 v2 standards and enables time synchronization across multiple devices. The solution supports IEEE 802.1AS profile making it ideal for TSN applications. Comcores timing solution supports IEEE 1588 PTP profiles such as IEEE Default and Peer-to-Peer, as well as ITU-T G.8275.1 and ITU-T G.8275.2 profiles.
The fully autonomously operated IP includes XGMII and GMII interfaces. User configuration allows easy configuration for various synchronization methods.
Time synchronization is crucial in many applications and industries, such as Wireless, Aerospace, Automotive, Industrial, and many others. Phase alignment method allows sub-nanosecond precision and enables even the most demanding applications, for example, 5G networks (Delivering timing accuracy in 5G networks whitepaper).

PTP profiles for 5G networks
Niklas Meyer Mortensen Jan 04 2022 The IEEE 1588 PTP standards provide a wealth of options and the basis for highly reliable and accurate time synchronization solutions. However, the time synchronization needs of specific applications in different industries can vary quite significantly. These specific needs are defined in separate PTP profile standards, often in collaboration with other industry standards organizations. For 5G, both IEEE and ITU-T provide relevant profiles that can be used to...
