製品説明
The PTP Transparent Clock (TC) from NetTimeLogic is a fully scalable implementation of a Peer-To-Peer, One-Step Transparent Clock according to IEEE1588. It contains a Peer-Delay message processors which answers and measures the Peer-Delay to its neighbors and an On-The-Fly-Modifier unit which corrects the residence time of PTP Event-Messages. Each port is individual and only some common counter is shared between the ports. The number of ports can be freely chosen according to the requirements.
All datasets and algorithms are implemented completely in HW.
It supports the following:
- P2P and E2E Delay Mechanism
- Layer 2 and Layer 3 (IPv4, IPv6) Transport Mechanisms
- Multicast, Unicast, Mixed
- Default Profile, Power Profile, Utility Profile, 802.1AS, ITU-G8265-1, ITU-G8275-1, ITU-G8275-2
