5GE PORT SWITCH WITH INTEGRATED GE COPPER PHY
FEATURES
SUMMARY OF BENEFITS
• Highest silicon integration level achieved for a 5-port, 10/100/1000
Ethernet switch device
• Seventh-generation switch on a chip
• Integrates:
Four 10/100/1000 transceivers (802.3ab compliant)
Five MACs (802.x compliant) with support for 9 Kbyte Jumbo Frames
One RGMII Interface and 128-Kbyte packet buffer memory
Nonblocking 5 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: <3.7W 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 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).
