TN1

TSN Ethernet Switch End Point (TSN-SE)

Time-Sensitive Networking (TSN) is a suite of IEEE 802.1 standards designed to enable deterministic, real-time Ethernet communications across industries ranging from Automotive, Aerospace, and Industrial to Medical and Governmental. These standards generally fall into three categories:

Time Synchronization: (IEEE 802.1AS)
Scheduling and Traffic Shaping: (IEEE 802.1Qav, IEEE 802.1Qbv)
Selection of Communications Paths and Fault Tolerance: (IEEE 802.1CB FRER)

Recognizing that each industry defines its own TSN “profile” (e.g., IEEE 802.1DP for Aerospace or IEEE 802.1DG for Automotive), NAI’s TN1 Ethernet Switched End Point (EP) module seamlessly incorporates these capabilities into the NAI Configurable Open Systems Architecture™ (COSA®). Built on the Xilinx XCU5CG-L1SFVC784I SoC, the TN1 module leverages DornerWorks-developed TSN IP to deliver reliable, high-precision Ethernet functionality. A dedicated TN1 software driver communicates over a PCIe x1 link to an SBC processor, providing a flexible foundation for synchronized, scheduled, and robust data transmission.

As TSN-based digital backbones continue to gain traction, the TN1 module enables straightforward system expansion and supports advanced applications—such as flight control, situational awareness, and data synchronization—while simplifying future scalability.
