Due to ongoing technological progression and underlying market dynamics, Gigabit Ethernet (GbE) technology with 10 Gigabit uplink speeds is starting to proliferate into the networking infrastructure across a multitude of different applications where elevated levels of connectivity are needed: SMB switch hardware, industrial switching hardware, SOHO routers, enterprise gateways and uCPEs, to name a few. The new Marvell® Link Street™ 88E6393X, which has a broad array of functionality, scalability and cost-effectiveness, provides a compelling switch IC solution with the scope to serve multiple industry sectors.
The 88E6393X switch IC incorporates both 1000BASE-T PHY and 10 Gbps fiber port capabilities, while requiring only 60% of the power budget necessitated by competing solutions. Despite its compact package, this new switch IC offers 8 triple speed (10/100/1000) Ethernet ports, plus 3 XFI/SFI ports, and has a built-in 200 MHz microprocessor. Its SFI support means that the switch can connect to a fiber module without the need to include an external PHY - thereby saving space and bill-of-materials (BoM) costs, as well as simplifying the design. It complies with the IEEE 802.1BR port extension standard and can also play a pivotal role in lowering the management overhead and keeping operational expenditures (OPEX) in check. In addition, it includes L3 routing support for IP forwarding purposes. Adherence to the latest time sensitive networking (TSN) protocols (such as 802.1AS, 802.1Qat, 802.1Qav and 802.1Qbv) enables delivery of the low latency operation mandated by industrial networks. The 256 entry ternary content-addressable memory (TCAM) allows for real-time, deep packet inspection (DPI) and policing of the data content being transported over the network (with access control and policy control lists being referenced). The denial of service (DoS) prevention mechanism is able to detect illegal packets and mitigate the security threat of DoS attacks.
The 88E6393X device, working in conjunction with a high performance ARMADA® network processing system-on-chip (SoC), can offload some of the packet processing activities so that the CPU’s bandwidth can be better focused on higher level activities. Data integrity is upheld, thanks to the quality of service (QoS) support across 8 traffic classes. In addition, the switch IC presents a scalable solution. The 10 Gbps interfaces provide non-blocking uplink to make it possible to cascade several units together, thus creating higher port count switches (16, 24, etc.).
This new product release features a combination of small footprint, lower power consumption, extensive security and inherent flexibility to bring a highly effective switch IC solution for the SMB, enterprise, industrial and uCPE space.
