PTP Transparent CLOCK

ISPCS proved

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 neighbours and an On-The-Fly-Modifier unit which corrects the residenz 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 choosen according to the requirements.

All datasets and algorithms are implemented completely in HW.
