8GE PORT SWITCH WITH INTEGRATED GE COPPER PHY

FEATURES

SUMMARY OF BENEFITS

• Highest silicon integration level achieved for an 8-port, 10/100/1000

Ethernet switch device

• Seventh-generation switch on a chip

• Integrates:

Four 10/100/1000 transceivers (802.3ab compliant)

Eight MACs (802.x compliant) with support for 9 Kbyte Jumbo Frames

Four RGMII Interfaces and 128-Kbyte packet buffer memory

Nonblocking 8-Gigabit Ethernet fully integrated switch fabric

SPI Interface for easy setup and smart unmanaged operation

• Classifies packets using four 802.1p QoS or DiffServ/TOS priority

queues

• VLAN 4k 802.1Q or port-based supported

• Supports up to 8k unicast MAC addresses

• Supports MAC-based port aggregation (trunking)

• Flow control: full-duplex (802.3x) and half-duplex options supported

• Supports automatic address learning and aging

• Internal oscillator circuit

• Low power 0.13 µm 1.2 V CMOS core: <3.8W Pd.

• Fanless operation supported

• Integrated voltage regulator for simplified power supply design

• 324-pin FBGA package (small form factor 19 mm x 19 mm)

• Enables a new generation of lower-cost switches with Gigabit Ethernet

connectivity and much smaller form factors.

• Uses field-proven industry-standard 10/100/1000BASE-T transceivers

which lowers overall system interoperability and reliability risks.

• Provides the most cost-effective Gigabit Ethernet connectivity to the

desktop for all remote, branch, and home office needs.

• 802.1Q tag VLAN, trunking, and 802.1p priority enables the switch to

be designed into a wide variety of applications from unmanaged to

smart switch.

• Jumbo frame support allows the device to be connected to corporate

server farms and networks while maintaining maximum TCP/IP

performance.

• CPUs are not required to initialize and run in cost-sensitive

unmanaged applications, providing true Plug and Play connectivity.

• Internal oscillator circuit simplifies design and reduces overall system

cost.

• On-chip HP auto-MDI/MDIX on all transceivers automatically detects

and corrects for crossover cables and allows direct switch-to-switch

connection.

• Lowest possible system cost through minimized number of

components.

• Higher system reliability and noise reduction due to elimination of

component with lowest MTBF (the fan).
