Time Sensitive Networking Switched Endpoint Core – TSN-SE

Time Sensitive Networking Switched Endpoint Core – TSN-SE

Time-Sensitive Networking (TSN) is a set of Ethernet sub-standards defined by the IEEE 802.1 TSN Task Group that improves the existing Ethernet specification towards time synchronization and deterministic communication in switched networks corresponding with given IEEE 802.1 and 802.3 standards.

The TSN Ethernet IP core TSN-SE provides TSN switched endpoint functionality and enables the integration of devices into networks complying with the TSN standards. An internal CPU port plus two external 10/100/1000+ Mbps and ports are available. It is also compatible with 10Base-T1S. The design equips a 1 GbE switching bar with cut-through capability. It provides time-sensitive networking for full-duplex point-to-point Ethernet communication. Accordingly, daisy chaining of devices or ring architectures as well as functional safe operation utilizing redundant links according to IEEE 802.1CB are enabled. The IP core consists of a switching bar, two instances of the TSN-EP IP and an additional routing logic optimized for low-latency communication. It can be used for switched devices in industrial automation, robotics, automotive, aerospace and more.
