OVERVIEW

The Marvell

88E6172/88E6176 devices are single-chip

integrations of a 7-port Gigabit Ethernet switches with

five integrated Gigabit Ethernet transceivers. This device

supports “Best in Class” Quality of Service (QoS) and the

highest “real world” performance. This device is uniquely

suited for Small Office Home Office (SOHO) and

Small-to-Medium Business (SMB) applications.

The device contains five 10/100/1000 triple speed

Ethernet transceivers (PHYs), one Gigabit SERDES

(88E6176 device only), and two digital interfaces that

support a combination of GMII, RGMII, MII, and RMII

interfaces in a 128-pin QFP package.

The device has a high-speed, non-blocking four traffic

class QoS switch fabric that uses the unique Marvell

Dynamic Queue Limit architecture. The QoS architecture

switches packets into one of four traffic class queues

based upon Port, IEEE 802.1p, IPv4 Type of Service

(TOS) or Differentiated Services (Diff-Serv), IPv6 Traffic

Class, 802.1Q VLAN ID, DA MAC address or SA MAC

address. The device also contains a high-performance

address lookup engine with support for up to 8K active

nodes, and a 1 Mbit frame buffer memory. Back-pressure

and pause frame-based flow control schemes are

included to support zero packet loss under temporary

traffic congestion. The MAC units in the devices comply

fully with the applicable sections of IEEE 802.3 and

support frame sizes up to 10KBytes.

The sixth and seventh ports’ interfaces support a direct

connection to Management or Router CPUs with inte-

grated MACs. These interfaces, along with BPDU han-

dling for IEEE 802.1D Spanning Tree Protocol, 802.1w

Rapid Spanning Tree, 802.1s Multiple VLAN Spanning

Tree, programmable per-port VLAN configurations,

802.1Q and Port States, support fully managed switches

and truly isolated WAN vs. LAN firewall applications. The

device supports 4,096 802.1Q VLAN IDs which can be

enabled on a per port basis. Three levels of 802.1Q

security is supported with error frame trapping and log-

ging.

The device supports multiple address databases (up to

4096), which allows packet routing without modification

of the MAC address. This allows the same MAC address

to exist multiple times in the MAC Address database with

multiple port mappings, to completely isolate the WAN

from the LAN database.

The 88E6176 device’s Gigabit SERDES interface sup-

ports SGMII, 1000BASE-X and 100BASE-FX. It can be

configured to act as the fifth or sixth port on the device.

The PHY units in the device support the latest 802.3az

Energy Efficient Ethernet (EEE) standard. They are

designed with Marvell

cutting-edge mixed-signal pro-

cessing technology for digital implementation of adaptive

equalization and clock data recovery. The device also

integrates MDI interface termination resistors into the

PHYs. This resistor integration facilitates board layout

and reduces board cost by reducing the number of exter-

nal components. Both the PHY and MAC units in the

devices comply fully with the applicable sections of IEEE

802.3, IEEE 802.3u, and IEEE 802.3x standards.

The PHYs also include an integrated Advanced Virtual

Cable Tester

(VCT™) enabling fault detection and

advanced cable performance monitoring.

The 88E6172/88E6176 also supports Wake-on-LAN and

Wake on Frame event detection allowing an attached

CPU to enter sleep mode and enabling even greater

system power savings.

Up to 12 LEDs can be directly driven by the device,

which supports both single and dual color LEDs. The

combining of multiple ports Link/Activity LED into a

single LED is also supported.

The devices many operating modes can be configured

using SMI (serial management interface - MDC/MDIO).

The devices also support a standalone QoS mode or

configuration via a low cost serial EEPROM.

The devices are designed for cost-sensitive Gigabit

Ethernet switch systems that require Quality of Service,

Trunking, Stacking, and/or Spanning Tree.
