Gigabit Ethernet LAN switches in several form factors
• Very low latency and advanced QoS enable seamless
integration of voice, video, and data traffic
• Built-in high-speed XAUI interfaces with Broadcom-unique
SerDes technology eases and accelerates system design, while
reducing cost and conserving board space
• Large internal data buffer memory eliminates the need for
expensive external memory
• Drives up to 10m of low-cost copper cables backplane and
stacking support
• Broadcom switch API compatibility enables reuse of resources
and fast time-to-market
TARGET APPLICATIONS
