16-Port Gigabit Ethernet Multilayer Switch
The BCM53716 series is a complete L2 SoC solution for easy and rapid
development of Gigabit switching applications. The BCM53716 series
uses a WebSuperSmart graphical user interface (GUI) for system
configuration of supported features. The BCM53716 integrates 16
configurable 1-Gbps ports or 10-Mbps/100-Mbps Ethernet ports.
The BCM53716 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 BCM53716 series supports auto-DoS attack prevention and
SNMP, IEEE 802.1x, spanning tree, and rapid spanning tree protocols.
The BCM53716 switch:
• Integrates internal memory in the common buffer pool (CBP) for
packet buffering.
• Provides 16-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.
• 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
• 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.
