BCM56334B1IFSBLG

The Broadcom BCM56334 is based on the industry-leading and market-proven StrataXGS IV product line. Each BCM56334 device is a highly integrated 24-port multilayer GbE switch with four ports of 10-GbE XAUI uplinks or four ports of 1 GbE/2.5 GbE uplinks. The GbE ports support SGMII as well as integrated SerDes for direct fiber (1000BX and 100FX) connectivity.The BCM56334 is purpose-built for nextgeneration Enterprise and Metro Ethernet access applications. This product family offers an 8-port or 24-port GbE configuration with uplinks. Two BCM56334 device can be connected together by two ports of 13G XAUI-over-HiGig stacking protocol to create a nonblocking 48-port switch.The BCM56334 supports nonblocking L2 switching and L3 routing, which are key features for Carrier Ethernet and enterprise networking applications.
