BCM53134
Six-Port Ultra-Low Power Gigabit Ethernet Switch

Overview
The BCM53134 is Broadcom's lowest power consumption integrated Ethernet switch for next-generation Home Gateway, SOHO/SMB and wireless router applications. Building on the industry-leading 28 nm 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.
The BCM53134 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 supports SP, WRR and WDRR scheduling (and mix of the three) and it supports both ingress and egress rate control (a.k.a. metering and shaping).
