Built-in SerDes
with SGMII support
The
BCM5690
network switch is a scalable, modular chip
solution with 12 ports. Each of these flexible ports supports
Gigabit Ethernet or 10/100 Mbps Ethernet. Additionally, the
BCM5690
supports both copper and fiber physical interfaces.
The
BCM5690
has a fully integrated SerDes functionality
consisting of a 10 Gbps XAUI HiGig Port, Gigabit Ethernet or a
SGMII PHY interface.
The 10 Gbps HiGig Expansion port supports explicit priority,
port trunking, and mirroring functions across switch elements.
The HiGig port can be used to interconnect upto 32
BCM5690s
making it extremely useful for highly-scalable network switch
applications.
The advanced fast filter processor (FFP) provides
ContentAware
TM
network processing per port. The FFP supports
ToS/DiffServ, rate limiting, policing, priority tagging, and
remapping. The advanced packet filtering and classification
functions of the
BCM5690
make it ideal for cutting-edge VoIP
and firewall applications.

The
BCM5690
supports advanced packet flow control such as
head-of-line blocking prevention and IEEE 802.3x compatible
full-duplex control. Moreover, the
BCM5690
supports a fully-
integrated data and address memory.
The
BCM5690
switch supports an I
2
C controller for
communicating with external devices such as serial EEPROM,
flash memories, and parallel port devices.
The modular switching architecture of the
BCM5690
embodies
the scalability, integration and performance features that a next
generation switch requires.
