P R O D U C T B R I E F Infineon’s PLB2224 is a highly integrated Layer 2+ switch-on-a-chip with twenty-four 10/100 Mbps and two 10/100/1000 Mbps Ethernet ports. The PLB2224 provides wire-speed, full-duplex switching capability on all ports. On-chip memory for packet buffers and address tables eliminate the need for external memory resulting in smaller PCB real estate and lower power consumption. The PLB2224 features support unmanaged, minimally managed (Smart), and fully managed Layer-2 switch configurations. The Gigabit ports can be used to daisy chain multiple devices in a system providing even higher port counts for medium to large office buildings and multi-tenant, multi-dwelling units where power and space are at a premium. The high level of integration in PLB2224 allows for design of systems with fewer components and a low bill of material. Features ■ ■ ■ ■ 24 + 2G Single Chip Switch On-chip Memory for Packet Buffer and Address Tables.
