Link StreetTM 88E6151/88E6181
5-Port/8-Port Gigabit Ethernet QoS Switches
88E6151/88E6181
The Marvell Link Street family of low power Gigabit Ethernet (GbE) switches provides industry leading functionality and price-performance ratio for the cost-sensitive Small Office/Home Office (SOHO) and enterprise desktop switching market. The Link Street 88E6151 (5-port) and 88E6181 (8-port) devices are GbE Quality of Service (QoS) switches integrating a high-performance switching fabric with five (88E6151) or eight (88E6181) SERDES ports. Each switch enables one port to be selected as a SERDES or as a fiber port that can directly drive a fiber module. Other advanced features include 802.1p/IPv4/IPv6 traffic classification, port-based VLANs, four priority queues, a high-speed address look-up engine, and 1 Mb of packet memory and MAC address storage. The Link Street 88E6151/88E6181 devices may be used in conjunction with Marvell Alaska Gigabit PHYs to build a three-chip complete Gigabit switch solution. The Link Street 88E6151/88E6181 switches perform wire-speed Gigabit switching and are ideal products for value-oriented enterprise-class desktop switches.

BENEFITS Provides a complete SOHO switching solution with true non-blocking switching performance and IEEE 802.1p QoS provisions Provide a glueless interface to Marvell Alaska Gigabit PHYs, including to the 88E1145 quad-port Gigabit PHY and the 88E1111 single-port PHY. Allows triple-speed Ethernet 10/100/1000 Mbps operation Enables the fiber port to drive a Gigabit fiber module directly Provides Layer 2 firewall port isolation Provides true non-blocking switching performance Supports a large number of Ethernet nodes Allow suppression or addition of group membership to provide flexible management by IT managers Supports the most number of traffic priority schemes in its class
Groups multiple links into one higher speed link Enables monitoring/analysis tools to monitor data from the network mirrored from each selected port
8 x SERDES
Link StreetTM-88E6151/88E6181 GbE QoS Switch
FEATURES BENEFITS
Multiple address data bases (up to 16) Chip configuration through SMI ports (MDC/MDIO) or by low-cost Serial EEPROM CMOS low power dissipation (typical 1.4W for 8-port)
APPLICATIONS
Allows packet routing without modification of the MAC address Provides an easy, low-cost switching configuration Eliminates expensive heatsinks or fans and permits the use of low cost and small enclosures
The Marvell Link Street family of products provides industry-leading functionality for Gigabit integrated switches. The 88E6181 device builds a complete 8-port Gigabit non-blocking QoS switch with all PHYs and memory in a 3-chip solution, when used with two 88E1145 Alaska Gigabit Quad PHYs. The 88E6151 device builds a 5-port Gigabit non-blocking QoS switch in a low-cost 4-layer PCB when used with five 88E1111 Alaska Gigabit Single-Channel PHYs; or alternatively, the 88E6151 product builds a smallest-board-space 3-chip solution when used with one 88E1145 Alaska Gigabit Quad PHY plus one 88E1111 Single-Channel PHY. The 88E6151 switchOs high integration, low power, and glueless interface to Marvell Gigabit PHYs save BOM costs and support many applications with few additional active components in a small footprint. The 88E6181 and 88E6151 switches have optimizations for fast packet switching and are ideal products for low cost enterprise-class desktop switches and SOHO networks.
