BCM5388

8GE PORT SWITCH WITH INTEGRATED GE COPPER PHY

8 Gigabit Ethernet Ports for SOHO and Subnetwork Applications

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)
