BCM53118 block diagram the BCM53118 is a highly integrated, cost-effective, gigabit switch. the switch design is based on the field-proven industry-leading bcm5398. the BCM53118 combines all the functions of a high-speed switch system, including eight full-duplex 10/100/1000base-t/tx ethernet transceivers, packet buffer, media access controllers (macs), and a non-blocking switch fabric, into a single 65-nm lp cmos device. in addition, the BCM53118 has on e 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 (gbe) devices. the BCM53118 is packed with features, including vlan, vlan double tagging, per port qos, jumbo frame support, dos prevent engine, per port rate control, and mibs management. it also includes two broadcom patented technologies, loopdtech and cablechecker, that are designed to lower the human effort for troubleshooting cable problems and loops during installation and for post-installation support. loopdtech also eliminates the additional cost of hardware and software required to run spanning tree protocol. cablechecker, unlike traditional tdr-based cable diagnostics, can detect cable and connector problems without disconnecting the cable from the other end. this allows cablechecker to run while the switch is passing packets. network support personnel can monitor and troubleshoot network problems remotely, which is very important in an smb environment, where it resources are scarce. loopdtech and cablechecker, when set up correctly, actually detect problems automatically without any human intervention. the BCM53118 has all the features required to enable residential gateways and home office switches that can be connected to voice, multimedia, and data devices simultaneously. with per-port qos/ queuing and rate control support, different packet types can be identified and prioritized within the switch, and voice packets can be assigned a higher priority for outbound delivery. memory manager 4 cos sp/wrr l2 tables gigabit mac 10/100/1000 mac for imp phy l2 processing BCM53118 1 gmii/rgmii 8 x ge phy
