The integration of a high-speed XAUI-compatible SerDes interface on each port reduces the complexity of board layout,
because it eliminates the need for a component to connect to an external SerDes chip. The SerDes interface connects to
both copper and fiber media. On StrataXGS 1-Gbps ports, SerDes runs at 1-Gbps. On StrataXGS 10-Gbps ports, four serial
channels, each running at 3.125 Gbps, are supported. SerDes delivers reduced signal traces, conserves board space,
consumes lower power than parallel interfaces, and delivers superior electromagnetic interference (EMI) performance (8b/
10b).
When StrataXGS 1-Gbps ports with integrated SerDes can connect to copper transceivers, they do so using Serial Gigabit
Media Independent Interfaces (SGMII), which reduces pin count to four, down from 25, compared with using Gigabit Media
Independent Interfaces (GMII). The reduced pin count lowers costs and simplifies design.

Broadcom will supply reference boards for a fully functional switch for evaluation and to jump-start a system vendor’s
development process. The BCM95690 SDK, for example, is available as a complete 24-port gigabit Ethernet Layer 2 – 7
SDK, and evaluation system based on the BCM5690 switch-on-a-chip.
The SDK provides a platform for accelerated software development and product evaluation. It includes a printed circuit board
with a typical configuration of two BCM5690s connected back-to-back and integrated to deliver 24 GE copper ports and two
optional fiber ports via GBICs. The SDK comes with the Wind River VxWorks real-time operating system, 19-inch rack-mount
chassis with Compact PCI backplane and power supply, and the latest version of the Broadcom API driver source code.
