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 integra-
tion in PLB2224 allows for design of systems with
fewer components and a low bill of material.
