描述 Description

The Marvell® Link Street®-88E6390X device is a single-chip, 11-Port Ethernet Switch with eight integrated 10/100/1000Mbps Ethernet transceivers and two high speed SerDes interfaces supporting 10Gbps XAUI and RXAUI, 2500-BaseX, 1000Base-X, and SGMII. The device also includes an integrated 200MHz microprocessor to enable smart or lightly managed switches without the need of an external CPU.\r
\r
The 88E6390X provides advanced Quality of Service (QoS) features with 8 egress queues. The high performance switch fabric provides line rate switching on all ports simultaneously while providing advanced switch functionality. The device includes a 256 entry TCAM to enable flexible switch policing, including Access Control Lists (ACLs) and Policy Control Lists (PCLs). The 88E6390X also supports the latest IEEE 802.1 Audio Video Bridging (AVB) and Time Sensitive Networking (TSN) standards. These new standards overcome the latency and bandwidth limitations of Ethernet to allow for the efficient transmission of real-time content for home, commercial, and industrial applications. These devices use the AVB/TSN technologies to identify and reserve the network resources for AVB/TSN traffic streams and supports precise isochronous streaming capability for reliable and quality audio/video transmission over Ethernet for today’s real-time, high definition information and entertainment options. The AVB/TSN protocols enable timing sensitive streams (such as digital video, audio, or industrial control traffic) to be sent over the Ethernet network with low latency and robust QoS guarantees.

应用 Application

The Marvell Link Street-88E63390X is the industry’s first true SOHO Ethernet switch chip to support 10Gbps interfaces. The addition of 10Gbps interfaces provides flexibility to support many different non-blocking switch configurations.\r
\r
• Unmanaged/Managed 8, 16, and 24-port Gigabit Switches Scalable architecture enables support for non-blocking high performance Gigabit switches with 10 Gigabit uplinks\r
• Smart and Lightly Managed Switches— Integrated microprocessor enables lightly managed switches with the addition of an external EEPROM\r
• Industrial Switches – Synchronous Ethernet, IEEE 1588v2, and 802.1 TSN support enable timing critical industrial networks
