8-Port GbE + 4-Port GbE Highly Integrated Multilayer Switch SoC
The BCM53312 is a complete L2 SoC solution for easy and rapid development of gigabit switching applications. The BCM53312 integrates 12 10/100/1000 wire speed switching processors. From a GPHY interface perspective, it integrates eight GPHYs and four SGMII SerDes cores. From a host interface perspective, it can use either embedded MIPS processors or a PCI interface for external processor connections.
The BCM53312 is a highly integrated solution ideally suited for stand-alone gigabit Ethernet switches. It combines all the functions of a high-speed switch system, including packet buffers, SerDes, media access controllers, address management, a non-blocking switch fabric, and an integrated high-performance CPU into a single 65 nm CMOS device. The BCM53312 supports auto DoS attack prevention and SNMP, IEEE 802.1x, Spanning Tree, and Rapid Spanning Tree protocols.
