Time Sensitive Networking (TSN) is the name of the IEEE 802.1 Task Group responsible for standards at Data Link Layer. This group provides the specifications that will allow time-synchronized and low latency streaming services through IEEE 802 networks. This set of protocols, deliver streams with guaranteed bandwidth and dterministic latency.

TSN is constantly evolving and it is targeting different sectors, like Automotive, Broadcasting or Aerospace. Therefore, this flexibility and reconfiguration can be only achieved through reconfigurable logic like FPGAs, HDL IPs and embedded software.

Our Multiport Time Sensitive Networking (MTSN) Switch IP core is a flexible HDL code ready to generate TSN end-point or bridge implementations. This IP Core is provided with a rich set of Generic parameters in order to obtain the best functionalities resources trade-off. This configuration of the TSN IP Core can be done through the Vivado GUI.
