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.
