BCM56503

Highly scalable BroadScale™ architecture evolved from five

generations of switching experience provide rich features,

scalability, and future proof solutions.

Optimized for secure-switching and convergence of applications

and services in the networks.

System vendors can build scalable high-performance, high-port

density GbE LAN switches in several form factors.

Multiple CoS and low latency enable the support of VoIP and

other voice, video, and data applications.

Built-in high-speed serial interfaces with Broadcom-unique

SerDes technology ease and accelerate system design, while

reducing cost and conserving board space.

Broadcom switch API compatibility enables software reuse and

faster time-to-market.

Small package and low power enables cost-effective and high-

performance system design.
