9-PORT GbE SWITCH WITH EIGHT INTEGRATED 10/100/1000 PHYs

•

Highly integrated, non-blocking 9-port 10/100/1000 switch silicon that

integrates:

• Eight 10/100/1000 PHYs

• One GMII/RGMII interface for an Inband Management Port (IMP) for

• Serial EEPROM, MDC/MDIO, SPI, and Interrupt-to-CPU interfaces

Broadcom’s LoopDTech™ and CableChecker™ help reduce network

downtime and minimize installation, maintenance, and support efforts

• LoopDTech technology provides loop detection without running

• CableChecker enables advanced cable diagnostics based on the

Virtual Local-Area Network (VLAN)

• IEEE 802.1Q-based VLAN with 4K entries

• Port-based VLAN

• VLAN double tagging (Q-in-Q)

Quality of Service (QoS)

• Four selectable QoS per port; SP and WRR

• Port, MAC, IEEE 802.1P, and IPv4/IPv6 DSCP based QoS

Performance

• 9 KB jumbo frame support; wirespeed performance for all fame sizes

• 4K MAC addresses with automatic learning and aging

• 256 multicast group support

• 196-KB packet buffer

Security

• IEEE 802.1x support for secure user authentication

• DoS prevention hardware

Traffic control and network resiliency

• Storm control and port-based ingress/egress rate control

• Spanning Tree support (Rapid Spanning Tree and Multiple Spanning

• IPv4 IGMP and IPv6 MLD snooping

• IEEE 802.3x programmable per-port flow control and backpressure

• Port mirroring, LLDP, LACP

Management

• On-chip MIB counters to collect receive and transmit statistics for each

Technology and physical specifications

• State-of-the-art 65 nm LP, 6-layer metal technology

• 1.2V core and 3.3V I/O

• Typical power consumption less than 3.9W

Flexible solution enables cost-optimized board and system designs.

Additional interfaces enable efficient designs for branch office switch

applications. Flexible CPU interface allows it to work with any CPU.

Broadcom-patented features provide unique solutions to network loop

and cable problems. LoopDTech, without running STP, automatically

detects loops, reducing system cost. CableChecker, unlike traditional

TDR-based cable diagnostics, can be run at any time to detect cable

length and problems without interrupting live traffic.

VLAN feature insures proper layer 2 isolation and security.

Double tagging enables private VLAN capability.

Supports all types of client connections, including VoIP, video,

multimedia, and data. Priority can be assigned each traffic type to

guarantee delivery of time-sensitive packets and efficient use of

network bandwidth.

Provides a bigger bang for the buck (with line-rate and non-blocking

performance in an SMB switch).

Highly integrated and scalable design supports large number of client

connections, prolonging the life of the switch even as the number of

users increases and, in turn, reducing the cost of network expansions.

Increases network security and blocks unwanted access.

Providess an easy way to troubleshoot security problems.

Enhances network security and resiliency to keep the network

running efficiently. A network that is always available and rarely goes

down enhances workplace efficiency and minimizes IT support costs.

Enables multicast switching with IGMP and MLD snooping without

expensive L3 multicast routing.

QoS, VLAN, and rate control, coupled with security, make the

BCM53118 one of the most powerful SMB switches to provide control

over who is connected, the resources assigned to the users, and

bandwidth management.

Can be managed remotely using SNMP or RMON. Build

sophisticated applications on the switch with the fully featured, easy-

to-use Broadcom SDK.

Leapfrogs one generation of process technology to provide the lowest

power and lowest system cost solution in the industry.
