MultiSync IP Core

Time-synchronized redundancy

The MULTIsync IP core is a multi-protocol redundant time synchronization core that provides sub-microsecond time synchronization, thus providing maximum flexibility for every situation. It is capable of providing time synchronization using IEEE 1588-2008 (PTPv2) and IRIG-B time synchronization protocols.

 

The MULTIsync IP core supports the following synchronized input sources:

  • PTP: Ethernet. PTP Slave on Input
  • IRIG-B: IRIG-B compliant signal. IRIG-B slave on input
  • Free-running timer: digital inputs

 

MULTIsync IP Core supports the following synchronization output options:

  • PTP: Ethernet. PTP master on the output
  • IRIG-B: IRIG-B compliant signals. IRIG-B slave on the outputs
  • Free Run Timer: Digital Outputs


This versatility allows the different use cases of MULTI synchronization to complement each other:

  • It can provide time synchronization redundancy so that the IP can be connected to both the PTP network and the IRIG-B master. Users can select one of the three available time sources (PTP, IRIG-B, free-running timer).
  • It can act as a PRIG to IRIG-B or IRIG-B to PTP bridge when the IP is synchronized with a selected master.
  • It can act as a PTP or IRIG-B master.

MULTI Synchronization can be used to introduce Ethernet traffic switching functionality or HSR and PRP redundancy in SoC-E HSR-PRP switches, TSN switches, unmanaged Ethernet switches, or IP core combinations for managed Ethernet switches.

Keeping up with the times and innovating - Explore more potentials of TSN with Hongke

Time Sensitive Networking (TSN) is a new generation of network technology based on the evolution of the standard Ethernet architecture. It takes traditional Ethernet as the network foundation and provides a data link layer protocol specification for deterministic data transmission capability through mechanisms such as clock synchronization, data scheduling, and network configuration. Compared with traditional Ethernet, TSN can provide microsecond-level deterministic services, reduce the complexity of the entire communication network, and realize the convergence of information technology (IT) and operation technology (OT). With its precise clock synchronization, deterministic traffic scheduling, and intelligent and open operation and maintenance management framework, TSN can ensure the high-quality transmission of multiple business traffic in a common network, and it has both performance and cost advantages, and it is the development trend of the future network. This is the future trend of network development.

Currently, TSN technology has a high level of discussion in the automotive, industrial, rail transportation, and aerospace fields. As a non-vendor-bound real-time communication protocol, we believe that TSN technology has a good application prospect.

Welcome to contact us to explore and learn the integration of TSN technology with various industries, and actively promote more applications on the ground to jointly build a new world of intelligent interconnection.
