The Marvell
®
88E6165 device is a single-chip 6-port
Gigabit Ethernet switch with five integrated Gigabit
Ethernet transceivers. This device supports ‘Best-in-
Class’ Quality of Service (QoS) and the highest ‘real-
world’ performance. The device is uniquely suited for
Small-to-Medium Business (SMB) and Access Switch
applications.
This device contains five 10/100/1000 triple speed
Ethernet transceivers (PHYs), two gigabit SERDES
interfaces, and GMII interfaces. The 88E6165 device
is designed to work in all environments. True Plug-
and-Play is supported with Auto-Crossover, Auto-
Negotiation, and Auto-Polarity in the PHYs, along with
bridge loop prevention (using Port States).
The 88E6165 device includes a unique Switch Bypass
mode to support router CPUs with 2 Gigabit MAC
interfaces. This bypass mode provides a dedicated
WAN interface that can connect to CPUs with GMII or
SGMII interfaces.
The device contains six independent 802.3 media
access controllers (MACs) supporting up to 10K byte
JUMBO frames, a high-speed, non-blocking four traffic
class QoS switch fabric that uses the unique Marvell
Dynamic Queue Limit architecture. The QoS architec-
ture 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 mem-
ory. Back-pressure and pause frame-based flow con-
trol 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.
The fifth and sixth ports’ optional GMII interface sup-
ports a direct connection to Management or Router
CPUs with integrated MACs. The sixth port also sup-
ports an RGMII interface that operates as a 1000
Mbps full-duplex port. These interfaces, along with
BPDU handling for IEEE 802.1D Spanning Tree Proto-
col, 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 logging.
The device supports multiple address databases (up
to 4096), which allows packet routing without modifica-
tion 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 PHY and SERDES units in the device are
designed with the Marvell
®
cutting-edge mixed-signal
processing technology for digital implementation of
adaptive equalization and clock data recovery. The
device integrates MDI interface termination resistors
into the PHYs. This resistor integration facilitates
board layout and reduces board cost by reducing the
number of external components. Special power man-
agement techniques are used to facilitate low power
dissipation and high port count integration. 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 device’s many operating modes can be config-
ured using SMI (serial management interface - MDC/
MDIO) or through in-band management via an Ether-
net frame. The device also supports a standalone QoS
mode or configuration via a low cost serial EEPROM.
The device is designed for cost-sensitive Gigabit
Ethernet switch systems that require Quality of Ser-
vice, Trunking, Stacking, and/or Spanning Tree.
