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.
