BROADCOM BCM53134MIFBG Ethernet Controller, Gigabit Ethernet Switch

BCM53134MIFBG is a six-port ultra-low power gigabit Ethernet switch. Building on the industry-leading 28nm RoboSwitch� architecture, the BCM53134 allows customers to significantly reduce power consumption of existing designs, while delivering higher performance to meet the growing bandwidth demands in the home and SOHO/SMB environments. It supports an advanced suit of features required by top tier service providers for home and SOHO/SMB gateways, especially in areas of VLAN bridging, QoS and Access-List classification. In the area of QoS, for example, the device supports six selectable classes of service per port, plus two additional time-sensitive classes. It supports Port based, IEEE 802.1P, TOS and DSCP-based CoS mapping. It has a rich feature set suitable for not only standard GbE connectivity for broadband home gateways, desktop, and laptop PCs, but also for next-generation gaming consoles, set-top boxes, networked DVD players, and home theatre receivers.
