PRODUCT OVERVIEW
The Marvell ¨ Link Streetª 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 Testerª (VCT) technology for advanced cable diagnostics, 1Mb of memory, and Spanning Tree support.

FEATURES
• Single-chip integration of a 7-port FE QoS switch
• Five integrated 10/100 Ethernet PHY ports and two MII ports
   - Two of the PHY ports can be conÞgured as copper or Þber
   - Multi-mode MII interfaces
• Virtual Cable Testerª(VCT) technology
• Automatic MDI/MDIX crossover for 100BASE-TX and 10BASE-T ports
• High-speed switch fabric
   - Integrated 1 Mb on-chip memory
   - High-performance look-up engine with support for up to 2,048 MAC address entries with automatic learning and aging
• QoS support with four trafÞc classes
   - QoS determined by destination MAC address, port ID, IEEE 802.1p tags, IPv4 Type of Service (TOS), Differentiated Services (DiffServ), and IPv6 trafÞc class
• Port VLAN and 802.1Q VLAN support
   - 802.1Q VLAN support for up to 64 VLANs
   - 802.1Q VLAN processing per port and VLAN tagging and untagging
• Multiple address databases (up to 16)
• SNMP and trafÞc snooping support
   - Extensive RMON statistics counters
   - IGMP snooping (IPv4) and MLD snooping (IPv6)
• Supports a low cost 25 MHz XTAL clock source
• CMOS low power dissipation PAVE = less than 1W

APPLICATIONS
   The Marvell Link Street family of products provides industry-leading functionality for low cost integrated switches. The 88E6063 switchÕs 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 deviceÕs voltage regulator to generate 1.5V and 2.5V from 3.3V.
