AVB MAC – SmartDV

AVB MAC

Design IP

Overview

SmartDV’s AVB (Audio Video Bridging) MAC IP delivers robust, time-synchronized data transmission for professional audio, video, and automotive infotainment systems. Fully compliant with IEEE 802.1 standards, including 802.1AS, 802.1Qav, and 802.1Qat, it enables reliable, low-latency, and high-throughput communication over standard Ethernet networks.

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. It integrates seamlessly into AVB-compliant networks, supporting features like time-aware shaping, stream reservation protocols, and precise clock synchronization.

Benefits

Time-Sensitive Networking for Real-Time Media – Supports AVB Endpoint talker and listener roles with IEEE 1722 Layer 2 transport for time-sensitive streaming
Precision Timing and Synchronization – Implements IEEE 802.1AS (gPTP) and IEEE 1588 with ingress/egress timestamping for accurate synchronization across devices
Advanced QoS and Traffic Shaping – Enables Class A, B, and C stream reservation (IEEE 802.1Qat), traffic shaping (802.1Qav), and QoS handling via 802.1Q and 802.1Qbb (PFC)
Flexible Network Configuration – Supports configurable Ethernet ports, rate limiting per port, VLAN tagging, and programmable IPG and preamble length
High-Performance MAC Capabilities – Cut-through switching, independent TX/RX MTU sizing, and configurable FIFO depths for optimized performance
Versatile PHY and SoC Interface Support – Compatible with GMII, RGMII, and MII interfaces for easy SoC integration

Compliance and Compatibility

Compliant with IEEE 802.3, IEEE 802.1AS, IEEE 802.1Qav, IEEE 802.1Qat, IEEE 802.1Qbb, IEEE 802.1BA, and IEEE 1722 standards
Supports IEEE 1588 PTP for precise timestamping
Compatible with all major EDA synthesis, simulation, and linting flows
