48-Port GbE + 6-Port 10-GbE Switch with BCM56803 and BCM56504
The BCM56803 network switch is a high-density 10-Gigabit Ethernet
switching chip solution with 12 ports. All 12 ports can flexibly support
HiGig2/HiGig+/HiGig/10-GbE/1-GbE. Additionally, the BCM56803
integrates all the SerDes required to interface with applicable copper and
fiber physical fabrics.
The integrated SerDes functionality includes 10-Gbps XAUI and 1-Gbps
SGMII PHY interfaces. The integrated SerDes complies with the CX-4
standard and PICMG3.1 standard, which ensures interoperability with
Ethernet line cards in an Advanced TCA chassis.
With 144 Gbps of aggregate switching bandwidth, the BCM56803 has
the highest level of Ethernet switching integration in the industry.
This integration allows embedded switching vendors to provide next-
generation products at 10-GbE speeds and is an ideal fit into current
design form factors. This capability has many benefits, including
reducing vendor development cost and adding value to current
generation systems through upgradability.
The BCM56803 device's low power dissipation simplifies board design
and optimizes vendor board space.
The advanced ContentAware engine supports ToS/DiffServ, policy-
based routing, priority tagging, and remapping. The advanced packet
filtering and classification functions of the BCM56803 make it a
seamless fit utility for computing applications where user segregation
and network security is critical.
In addition, the BCM56803 provides advanced security features that
improve network resiliency and reliability. Moreover, the BCM56803
features advanced load-balancing functionality that uses flow
information to provide high percentage link utilization.
The BCM56803 supports Layer 2 switching with 4K VLANs, IPv4, and
IPv6 full routing functionality, enabling it to be a direct extension of the
enterprise network. This functionality provides additional customer
value by eliminating the hardware and management costs of maintaining
intermediate routers.
As the latest member of the StrataXGS switch family, the BCM56803
software development kit preserves software continuity with Gigabit
Ethernet switches, reducing development cost and shortening the
product time-to-market.
The BCM56803 implements congestion handling features such as
Congestion Notification and IEEE 802.3x flow control.
In addition to a 32-bit PCI interface used to communicate with a local
CPU, the BCM56803 supports an I
2
C controller, which communicates
with external devices such as serial EEPROM, flash memories, and
parallel port devices.
The BCM56803 relies on Broadcom’s modular switching architecture to
provide intelligent packet processing, network security, and enhanced
manageability at a low cost. The BCM56803 is an ideal solution for next-
generation, high-speed embedded switching applications, such as blade
servers and Advanced TCA computer platforms.
Together with the BCM56500 series, the BCM56803 can be used to
build cost-effective, high-density GbE and 10-GbE switches.
