General Description
The Broadcom BCM5670 switch fabric is the central component of the
modular and highly scalable StrataXGS Gigabit Ethernet switch
architecture. StrataXGS components can be applied in a wide variety of
configurations, enabling system designers to strategically balance cost,
port density, and performance in the products they build.
Highly Integrated
The integration of Broadcom’s robust XAUI-compatible serializer/
deserializer (SerDes) interface on each BCM5670 port reduces board
complexity. The XAUI interface can be used to route high speed signals
across 44 inches of FR4, connectors, and backplanes. SerDes technology
also enables the use of inexpensive cables for stacking applications.
Superior Performance
The BCM5670 delivers wire speed switching performance across all of
the ports simultaneously. The effective bandwidth of each HiGig

interface is 20 Gbps (10 Gbps, full-duplex). The BCM5670 switch fabric
interconnects other StrataXGS component chips across a 160-Gbps
backplane. It introduces very low switching latency, enabling the high
quality transmission of voice, video, and data traffic.
Flexible Management
The BCM5670 HiGig switch links to a host CPU through a PCI bus at
speeds of up to 66 MHz. Bus mastering and advanced DMA are
supported in hardware for the efficient exchange of packet data between
CPU memory and the BCM5670 switch.
The BCM5670 switch can also work without host CPU support, using an
I
BCM5632 chip can link to a BCM5670 via an XGMII-to-XAUI
converter, such as the BCM8011. As many as 15 BCM5632 chips can be
interconnected, providing up to 180 Gigabit Ethernet ports.
