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 OfTce/Home OfTce (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, Tve 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 conTgured as copper or Tber

- Multi-mode MII interfaces

? Virtual Cable Testera(VCT) technology

? Automatic MDI/MDIX crossover for 100BASE-TX and 10BASE-T ports

? SNMP and trafTc 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 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 ?exibility of the 88E6063 switch comes from its conTguration 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.
