APPLICATIONS
The Marvell Link Street family of products provides industry-leading functionality for low cost integrated switches. The 88E6083
switchÕs high integration, low power and two extra ports saves BOM costs and supports many applications with few additional
active components in a small footprint. The Link Street 88E6083 device is a 10-port QoS switch integrating a high-performance
switching fabric with four priority queues, a high-speed address look-up engine, eight 10/100 Ethernet digital PHY ports, two MII
ports, ten independent MACs, VCT technology for advanced cable diagnostics, 1Mb of memory, and Spanning Tree support. Other
advanced features include 802.1p/IPv4/IPv6 trafÞc classiÞcation, 802.1Q VLAN, extensive RMON counters and special power
management techniques for lowest power dissipation. The 88E6083 switch has optimizations for faster packet routing and is an
ideal product for low cost enterprise-class desktop switches, advanced broadband gateway routers and Multi-Tenant Unit (MTU)
gateways. The ßexibility of the 88E6083 switch comes from its conÞguration options and integration. The device supports an
optional EEPROM to override any desired QoS default settings. The 88E6083 switch contains PHYs, LED drivers, voltage regulator
logic, QoS switch logic, and memory. The only active components required to implement a complete 88E6083 10/100 Ethernet
switch are a 25 MHz crystal clock source and two low cost PNP transistors used by the 88E6083 deviceÕs voltage regulator to
generate 1.5V and 2.5V from 3.3V.
The Marvell Link Street 88E6083 FE switch comes with a complete set of hardware and software
development tools to assist network hardware engineers with product evaluation. MarvellÕs worldwide Þeld applications engineers
collaborate closely with network equipment vendors to develop and deliver new competitive products to market on time. Marvell utilizes
recognized world-leading semiconductor foundry and packaging services to reliably deliver high-volume and low cost total solutions.
