• Manufacturer Part Number: BCM567X
• Description: A Scalable Approach to Gigabit Ethernet Switch Design
• Manufacturer: BOARDCOM [Broadcom Corporation.]

Another product, the BCM5691, supports 12 GE ports but no uplink, for use in standalone configurations. Both the BCM5690
and BCM5691 support a standard PCI bus for moving signals to and from the CPU and, in the case of the BCM5690, to a
PCI uplink.
StrataXGS chips are highly programmable, in that system designers can add value and differentiate their companies’
products by activating certain features with minor development work in software. Using the Broadcom API, new features are
easily added to the existing chip.
