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 9kByte Jumbo Frames
4 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 4 802.1p 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: <5W 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-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 tranceivers 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)
