Overview

The PTP Hybrid Clock (HC) from NetTimeLogic is a combination of NetTimeLogic's PTP Transparent Clock (TC) and PTP Ordinary Clock (OC). It adds the Sync and Announce message processors to the design which allow synchronization of the clock according to IEEE1588 while keeping the timing aware frame forwarding feature of the TC. 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 HC is intercepting the path between an Ethernet PHY and an Ethernet core that forwards or handles Ethernet frames. Mostly this is used in daisy-chained networks. This allows message injection in parallel to data transfers from/to the Switching Core.

All datasets and algorithms are implemented completely in HW.

NetTimeLogic offers full time synchronization, network redundancy, and time sensitive networking solutions as vendor independent FPGA IP cores and design services in these fields. We provide full hardware implementations of synchronization IP cores such as PTP-Transparent-, Ordinary-, Grandmaster- or Hybrid-Clocks as well as IRIG-, PPS-, NMEA-Masters and Slaves, a NTP Server and Client and a RTC-Master and a DCF-Slave. For network redundancy we provide a full hardware implementation of the HSR and PRP protocols and for time sensitive networking we provide also a full hardware implementation of TSN suporting all major standards. All IP cores can be combined to a complete synchronization or network redundancy solution which can act e.g. as bridge between the different times synchronization protocols or as a network redundancy solution with time synchronization support. We also offer design services in the field of FPGA and Embedded Software development. With our 20+ years of experience and certification in FPGA and software development as well as product and project management we bring in our expertise to design the best possible solution for you. We understand your needs and can give you support to develop a best in class product. We offer swiss quality engineering - highest quality, always on time!
