MANAGED SWITCH WITH 16 FE PORTS + 2-GbE INTERFACE

The BCM53212M is a ninth generation RoboSwitch™ design based on the field-proven BCM5320 device. This integrated 0.13µ-CMOS device combines all the functions of a high-speed Switch system including packet Buffers PHY transceivers, Media Access Controllers (MACs), address management, and a non-blocking Switch fabric. It is designed to be fully compliant with the IEEE 802.3 and IEEE 802.3x specifications, including the MAC control pause frame, auto-negotiation and with all industry standard Ethernet and Fast Ethernet devices. The BCM53212M contains 16 full-duplex 10BASE-T/100BASE-TX Fast Ethernet Transceivers with advanced cable diagnostics support. Each performs all of the physical layer Interface functions for 10BASE-T Ethernet on Category 3, 4, or 5 Unshielded Twisted Pair (UTP) cable and 100BASE-TX Fast Ethernet on category 5 UTP cable. In addition, the BCM53212M has two GMII/RGMII/TBI Interfaces that provide flexible 10/100/1000BASE-TX/FX connectivity. An additional MAC is included for CPU connection via RvMII or MII Interface The BCM53212M has a rich feature set suitable for streaming VoIP, Video and data traffic for Multimedia applications. The BCM53212M supports up to four QoS queues per port. Traffic QoS CAN be assigned based on Port-ID, MAC address, 802.1p or DiffServ. Together with 4K entries, 802.1Q VLAN, 802.1x EAPOL protocol filtering, MAC-based link aggregation with dynamic failover, per-port bandwidth/rate control, MAC address locking, and IGMP/MLD snooping at Layer 3 allow system vendors to build advanced L2+ Switch systems for the Multi- Tenant/Multi-Dweller Unit (MTU/MDU) markets. The BCM53212M provides 70+ on-chip MIB Counters to collect receive and transmit statistics for each port. By Broadcom Corp.
