48-Port Gigabit Ethernet Multilayer Switch
The BCM53718 series is a complete L2 SoC solution for easy and rapid
development of Gigabit switching applications. The BCM53718 series
uses a WebSuperSmart graphical user interface (GUI) for system
configuration of supported features. The BCM53718 integrates 48
configurable 1-Gbps ports or 10-Mbps/100-Mbps Ethernet ports, with
the BCM53718S adding support for two Gigabit uplink ports.
The BCM53718 series is a highly integrated solution ideally suited for
stand-alone Gigabit Ethernet switches. It combines all the functions of a
high-speed switch system, including packet buffers, SerDes, media
access controllers, address management, a non-blocking switch fabric,
and integrated high-performance CPU into a single 0.13 µm CMOS
device. The BCM53718 series supports auto-DoS attack prevention and
SNMP, IEEE 802.1x, Spanning Tree, and Rapid Spanning Tree
protocols.
The BCM53718 switch:
•
Integrates internal memory in the Common Buffer Pool (CBP) for
packet buffering.
•
Provides 48-full-duplex GbE ports that interface to external physical
layer devices via the SerDes or SGMII interface. The GbE ports
support both copper and fiber media.
•
Provides additional 2 x 1 GbE uplink ports for BCM53718S.
•
Supports a Broadcom serial control (BSC) controller for
communicating with external devices such as serial EEPROM, flash
PROM memories, and parallel port devices.
•
Supports a serial interface for the MII management of physical layer
devices.
•
Supports an integrated MIPS processor for management functions
with a DDR memory controller, a CMIC for switch access, parallel
flash interface for booting, two serial UART interfaces, and eight
GPIO pins.
•
Contains memory required to host L2 switching tables.
•
Supports VLAN double tagging via Gigabit ports.
•
Supports advanced QoS shaping for service provider networks.
•
Integrates sophisticated metering, statistics, and traffic management
features, optimizing the QoS for voice, video, and data convergence.
