SmartDV’s Ethernet TSN MAC IP is a silicon-proven, fully featured Time-Sensitive Networking Media Access Controller solution purpose-built for SoC designs requiring deterministic, low-latency Ethernet across automotive zonal architecture, industrial automation, and professional audio/video applications. Fully compliant with IEEE 802.3-2022 and the core TSN standard suite, it delivers speed-independent TSN MAC functionality applicable across 10 Mbps through multi-gigabit Ethernet rates, giving SoC teams a single deterministic MAC architecture that scales across the full range of TSN-enabled network speeds rather than being tied to a single physical layer rate.
Designed to address the demanding determinism and reliability requirements of modern time-sensitive networks, the IP implements IEEE 802.1Qbu frame preemption together with IEEE 802.3br Interspersing Express Traffic, IEEE 802.1AS-2025 (gPTP) and IEEE 1588-2008 (PTP) timing synchronization, IEEE 802.1Qbv scheduled traffic shaping and IEEE 802.1Qav credit-based shaping, IEEE 802.1Q class-based flow control with 8 traffic classes, and IEEE 802.1CB frame replication and elimination for reliability. Its full and half duplex support, VLAN frame handling, cut-through switching, and independently enable/disable TSN feature architecture give automotive and industrial SoC teams a production-tested, spec-complete TSN MAC implementation adaptable to any underlying Ethernet PHY speed.
Built for design flexibility and silicon efficiency, the IP core is highly configurable for both ASIC and FPGA implementations, with a strong focus on area optimization, power management, and peak performance. Its ultra-low latency, compact implementation and clean host interface enable fast integration across a wide range of automotive and industrial process nodes.
