The Marvell Link Street family of products provides industry-leading functionality for low cost integrated switches. The 88E6063 switch's high integration, low power, and two extra ports save BOM costs and support many applications with few additional active components in a small footprint. The ßexibility of the 88E6063 switch comes from its conÞguration options and integration. The device supports an optional EEPROM to override any desired QoS default settings. The 88E6063 switch contains PHYs, LED drivers, voltage regulator logic, QoS switch logic, and memory. The only active components required to implement a complete 88E6063 10/100 Ethernet switch are a 25 MHz crystal clock source and two low cost PNP transistors used by the 88E6063 device's voltage regulator to generate 1.5V and 2.5V from 3.3V.

The Marvel^® Link Street^{TM 88E6063} family of low power Fast Ethernet (FE) switches provides industry-leading functionality and price-performance ratio for the cost-sensitive Small OfÞce/Home OfÞce (SOHO) gateway/switching market and enterprise desktop switching market. The Link Street 88E6063 device is a 7-port Quality of Service (QoS) switch integrating a high-performance switching fabric with four priority queues, a high-speed address look-up engine, Þve 10/100 Ethernet digital PHY ports, two MII ports, seven independent Media Access Controllers (MACs), Virtual Cable Tester^TM (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 88E6063 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.
