Hot-selling and scarce BCM56321B1IFSBG 12 GIGABIT + 1 10-GIGABIT SWITCHING PROCESSOR BGA spot stock

Product Descriptions

• Complete switch on a chip integrates 12 10/100/1000 and one 10G Ethernet Media Access Controllers (MACs) supporting RMII, GMII, XGMII and TBI interfaces, including multi-layer forwarding and filtering logic and internal ARL tables and packet buffering.

• Supports 32K internal MAC addresses, which are shared by all ports. Multicast MAC addresses, including IP multicast, can also be stored and

searched.

• Supports Quality of Service (QoS). Each output port has four priority queues and their assignment can be based on DiffServ TOS field or the 802.1p priority field.

• Filters and forwards traffic at full wire speed on all 13 ports at all layers of functionality. This equates to 44 Gbps of bandwidth.

• Provides a mechanism to bundle together up to 12 ports at the same speed to form a port bundle or a trunk group, establishing up to six trunk ports.
