TSN Multiport Switch Core – TSN-SW

Being developed by the IEEE, Time Sensitive Networking (TSN) is a set of standards aimed at integrating determinism in switched Ethernet networks according to existing IEEE 802.1 and 802.3 standards. In essence, TSN targets to realize Ethernet networks with guaranteed end-to-end latencies for real-time critical data traffic, transmission of (time-) critical and uncritical data traffic over a converged network, low packet losses and low latency fluctuation (jitter).

The TSN-SW IP Core is suitable for multiport switch devices within TSN Ethernet networks. An internal CPU port and additional up to 24 external 10/100/1000+ Mbps are available. It is intended for devices in industrial automation, robotics, automotive, aerospace and more.
