Benefits
• High level of integration in a low-power, low-latency
small-footprint package makes the Fujitsu 10GbE switch
ideal for backplane switch fabric applications
• Adaptive-equalization algorithm eliminates the need for
an external re-timer circuit in CX4 cabling, saving board
space, power, latency and cost
• Integrated, programmable, high-speed SerDes allows each
port to be either 10Gbps serial, XAUI or CX4 capable,
giving system designers added flexibility
• Redundant Gigabit Ethernet ports gives users a high-
availability, agonistic management interface that is not
tied to any particular processor chip
• 10Gbps serial capabilities enable the use of XFP modules
without requiring third-party SerDes chips. This reduces
board space, latency, cost and power consumption
• On-chip micro-engine increases flexibility and simplifies
software development, reducing time to market
• Backplane 10Gbps serial capabilities enable designers to
use fewer physical backplane fabric connections
Applications
• Embedded, next-generation, high-density backplane
switching applications
• microTCA MCH applications
• Low latency interconnects for cluster computing
• Blade-server switching applications
• Advanced TCA carrier-board backplane fabric

The Fujitsu 20-port 10Gbps Ethernet Switch Chip
Description
Fujitsu’s next-generation high-density switch chip embeds
20 high bandwidth, full-duplex 10 Gbps ports into a single,
integrated, small-footprint package. Each port has the
flexibility to support either 10Gbps serial, XAUI or CX4.
In addition, the adaptive equalization capability on each port
can increase reach for XAUI, CX4 and 10Gbps serial
applications, as well as eliminate the need for external
re-timer circuits, reducing board space, power consumption
and cost.
As a result of being fabricated with 90nm technology, the
MB8AA3020 provides the lowest-power-consumption
highest-density 10GbE switch chip in the industry, making
the MB8AA3020 well suited for high density, low-power
applications.
The Fujitsu MB8AA3020 20-port 10GbE switch chip
provides eight priority classifications per port, which allows
priority switching based on DiffServ, MAC address, VLANs,
extended VLANs and ports. The MB8AA3020 also provides
several carrier-grade Ethernet features including priority
PAUSE, backward congestion notification, and early-class
watermark capabilities for congestion notification. These
features in combination with its large buffer memory, allow
the MB8AA3020 to handle both best-effort and guaranteed-
high-availability customer traffic in a single chip.
With 10Gbps serial capabilities on each port, the
MB8AA3020 allows direct connection to optical XFP
modules on any port, eliminating the use of third party
SerDes chips. This reduces board complexity, improves cost,
and reduces time to market.
MB8AA3020 offers a total of 400Gbps of non-blocking
aggregate switching capacity in both cut-through and
store-and-forward mode of operation. A switching latency of
300ns, including 10GbE SerDes in cut-through mode, makes
the switch ideally suited for high-density, latency-sensitive
applications.
In addition to its standard 4K VLAN and Q-in-Q capabilities,
the chip provides 64 additional user VLAN addresses, which
can be used to logically partition a network without the use
of Q-in-Q.

MB8AA3020
The MB8AA3020 possesses two 10/100/1000 Ethernet
management interfaces, which provide an agnostic interface
to the chip, allowing it to communicate with any third-party
processor chip. The MB8AA3020 also supports I C
interfaces, MDIO interfaces and EEPROM interfaces for
low-speed communication with third-party external devices.
The Fujitsu MB8AA3020 module is the industry’s most
advanced, high-density switching architecture, providing
a low-latency, low-power, feature-rich switch in a small
form-factor footprint. The MB8AA3020 is well-suited for
next-generation backplane fabric applications seen in
AdvancedTCA, µTCA and blade server platforms.
