PHY 1-CH 5-Port 457-Pin F-BGA

The BCM5395 is a highly integrated, cost-effective Gigabit switch. The BCM5395 combines all the functions of a high-speed switch system, including five full-duplex 10/100/1000 BASE-T/TX Ethernet transceivers, packet buffer, Media Access Controllers (MACs), and a non-blocking switch fabric into a single 0.13µ CMOS device. In addition, the BCM5395 has one GMII/RGMII/MII/RvMII interface for a CPU or a wireless/DSL/cable router chip. It complies with the IEEE 802.3 and IEEE 802.3x specifications, including the MAC control pause frame, providing compatibility with all industry-standard Ethernet, fast Ethernet, and Gigabit Ethernet devices.The BCM5395 is packed with features, including VLAN, VLAN double tagging, per port QoS, jumbo frame, rate control, and MIBs management. Most importantly, it includes two Broadcom patented technologies, LoopDTech and CableChecker, that are designed to troubleshoot cable problems and loops during installation. Unlike traditional TDR-based cable diagnostics, Broadcom CableChecker, can detect cable and connector problems without having to disconnect the cable from the other end. This means CableChecker can be running while the switch is passing packets. With Broadcom WebSuperSmart, a web-based management interface, network support personnel can monitor and troubleshoot network problems remotely, which is very important in SMB environment where IT resources are scarce.LoopDTech and CableChecker, when set up correctly, actually detect problems automatically without any human intervention. The BCM5395 can be smart-managed with Broadcom WebSuperSmart, which can be provided by Broadcom and customized for system vendors. Broadcom"s turnkey solution approach (silicon chip, reference boards, and management software) greatly accelerates time-to-market for customers.The BCM5395 has all the features needed to enable SMB in a box, which can be connected to voice, multimedia, and data devices all at once. With the support for per port QoS/queuing and rate control, different packet types can be identified and prioritized within the switch, and voice packets can be assigned with higher priority for outbound.
