Ethernet Switch 7-Port 100Mbps

Optimized for L2 switching, the BCM53101 is a feature-enhanced seven-port switch to the industry-leading BCM5325E RoboSwitch. This device combines all the functions of a high-speed switch system, including packet buffers, PHY transceivers, MACs, address management, and a non-blocking switch fabric, into a 65 nm LP process. The BCM53101 contains five full-duplex 10BASE-T/100BASE-TX Fast Ethernet transceivers connected to the five on-chip 10/100 MACs. In addition, a sixth 10/100 MAC is available through the MII/RvMII interface. The BCM53101 also features a 10/100/1000 MAC, which can be used to connect to an external CPU via the RGMII/MII/RvMII interface. The BCM53101 also integrates several gigabit-class features such as 4Kentry VLAN, 2K-entry MAC addresses, ingress rate limiting and egress rate shaping, port mirroring, IGMP/MLD snooping, and trap reserved MAC addresses to CPU, among others. The BCM53101 is designed from the ground up for lower power consumption. The power-efficient on-chip PHYs help lower power consumption by over 50% compared to its predecessor, the BCM5325E. Fabricated using 65 nm LP process, the device consumes less than 0.7W. Additionally, the BCM53101 incorporates several green modes such as auto-power down, sleep mode, and a deep sleep mode (needs external CPU).
