OVERVIEW

The BCM5691 network switch is a scalable, modular chip solution with 12 ports. Each of these flexible ports supports Gigabit Ethernet or 10/100 Mbps Ethernet. Additionally, the BCM5691 supports both copper and fiber physical interfaces. The BCM5691 has a fully integrated SerDes functionality consisting of a Gigabit Ethernet or a SGMII PHY interface.
