BCM5388 ® 8GE PORT SWITCH WITH INTEGRATED GE COPPER PHY SUMMARY OF BENEFITS FEATURES • Highest silicon integration level achieved for an 8-port, 10/100/1000 Ethernet switch device • Enables a new generation of lower cost switches with Gigabit Ethernet connectivity and much smaller form factors. • • Seventh-generation switch on a chip • 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. Supports up to 8k unicast MAC addresses • Internal oscillator circuit simplifies design and reduces overall system cost. Supports MAC-based port aggregation (trunking) • 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) 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 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.
