Topaz Switch

Topaz – 6 Port GE Switch with 2.5Gbps Serdes


The Marvell® Link Street®-88E6341 device is single-chip, 6-Port Ethernet Switch with four integrated 10/100/1000Mbps Ethernet transceivers and one high speed SerDes interfaces supporting 2500-BaseX, 1000Base-X, and SGMII. The device also includes an integrated 200MHz microprocessor with 60Kbytes of internal memory to enable smart or lightly managed switches without the need of an external CPU.

The 88E6341 provides advanced QoS features with 4 egress queues.  The high performance switch fabric provides line rate switching on all ports simultaneously while providing advanced switch functionality.  The device includes a 128 entry TCAM to enable flexible switch policing, including Access Control Lists (ACLs) and Policy Control Lists (PCLs).   The 88E6341 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 quality of Service guarantees.
