ISPCS proved

The PTP Ordinary Clock (OC) from NetTimeLogic is an extention to a single port of NetTimeLogic's PTP Transparent Clock (TC). It adds the Sync and Announce message processors to the design which allow synchronization of the clock according to IEEE1588.  The OC will run in Slave or Master mode according to the configuration and Best-Master-Clock (BMC) algorithm. For resource optimization the OC can also be implemented as Slave-Only clock.

The OC is intercepting the path between an Ethernet PHY and an Ethernet MAC. This allows message injection in parallel to data transfers from/to the MAC.

All datasets and algorithms are implemented completely in HW.
