The PTP Hybrid Clock (HC) from NetTimeLogic is a combination of NetTimeLogic's PTP Transparent Clock (TC) and PTP Ordinary Clock (OC) according to IEEE1588-2019 (PTP). It is intended mainly for daisy-chain applications but can also wrap other non-deterministic Ethernet cores/devices like Bridges, Switches, or Redundancy Nodes, and runs the whole protocol handling, algorithms, and calculations are implemented in the core, no CPU is required, which allows running PTP synchronization completely independent and standalone. The HC can run again as Master or Slave with E2E or P2P as delay mechanism and supports the following PTP Profiles: Default Profile, Power Profile, Utility Profile, TSN Profile (802.1AS) and ITU Profiles (ITU-T-G82651/G82751/G82752)
