Seven-Port Integrated GbE Energy-Efficient Ethernet™ Switch

Currently Viewing:

Integrated multilayer switch, supports the IEEE 802.3az specification for EEE.
The BCM53125 is the optimal solution for Small and Medium Business (SMB) designs that have challenging low-power requirements. Building upon industry-leading 65 nm RoboSwitch™ architecture, the BCM53125 can lower the power consumption by an additional 10 percent when compared to the previous-generation device. The BCM53125 solidifies Broadcom's leadership in Ethernet switching technology by delivering an optimized solution for the SMB desktop switch, wireless router and gateway markets.
