Ethernet 100G TSN MAC IP – SmartDV

Ethernet 100G TSN MAC IP

Design IP

Overview

SmartDV’s Ethernet 100G TSN (Time-Sensitive Networking) MAC IP Core is a specialized, high-performance solution that enables deterministic and low-latency data communication for mission-critical applications. Tailored for industrial automation, automotive Ethernet, and 5G transport networks, it combines IEEE 802.1 TSN features with 100G Ethernet performance to support synchronized, time-aware data transmission.

The IP core is compliant with IEEE 802.3 and incorporates key TSN capabilities such as time-aware shaper (TAS – IEEE 802.1Qbv), frame preemption (IEEE 802.1Qbu/802.3br), scheduled traffic, and precise time synchronization (IEEE 802.1AS). It also supports VLAN tagging, traffic classification, and ingress policing for enhanced traffic control and QoS enforcement.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. Integrated with standard PHY interfaces like XLGMII and CGMII, the 100G TSN MAC IP enables scalable deployment in systems that require ultra-reliable and time-sensitive communication.

Benefits

Standards-Based Deterministic Networking – Compliant with IEEE 802.3-2022 and TSN standards for high-speed, low-latency, and deterministic Ethernet communication
Integrated TSN Features – Supports IEEE 802.1Qav Credit-Based Shaper (CBS), 802.1Qbv Time-Aware Shaper (TAS), and 802.1AS for time synchronization
High-Performance 100G MAC Engine – Offers full-duplex 100G operation with CGMII and optional support for XLGMII/AXI-Stream interfaces
Precise Time Control and Scheduling – Enables accurate time stamping, gated transmissions, and per-stream shaping for real-time traffic enforcement
Seamless Integration with SmartDV PCS IP – Designed to integrate directly with SmartDV’s 100G PCS core to enable end-to-end TSN pipelines
Traffic Classification and VLAN Support – Supports IEEE 802.1Q VLAN tagging, including PCP (Priority Code Point) for traffic classes and stream identification
