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