The 88E6321-A0-NAZ2I000 is a Marvell 7-port Gigabit Ethernet AVB switch device with TCAM, integrating two Gigabit Ethernet PHYs, two Ser Des interfaces and three RGMII ports, supplied in a 108-pin QFN package. It is an industrial-grade orderable part. AVB (Audio Video Bridging) is the IEEE 802.1 set of extensions that adds time synchronization, traffic shaping and stream reservation to standard Ethernet so that audio and video streams get bounded latency. The integrated TCAM allows per-flow classification and filtering rules to be applied in hardware at line rate.

AVB-capable switch devices are used where Ethernet must carry time-sensitive streams alongside ordinary traffic: automotive in-vehicle networks and infotainment backbones, professional audio and video distribution, broadcast and live-production equipment, industrial automation with deterministic control loops, and rail and transportation networks. The mix of integrated PHYs, Ser Des and RGMII ports lets one device serve copper front ports, optical or backplane links, and a host processor connection simultaneously. Buyers are automotive tier-one suppliers, professional AV and broadcast equipment manufacturers, industrial networking OEMs, and sourcing teams supporting existing Marvell-based designs.
