Broadcom introduced its next generation family of single-chip 65 nanometer (nm) Ethernet switching chips for OEMs designing modular, stackable and fixed form factor equipment for the service provider, data center, and enterprise markets. Broadcom’s 4th generation StrataXGS architecture utilizes a low power, 65nm CMOS process. Two new devices are being announced:
- The Broadcom BCM56624 — a 48-port Gigabit Ethernet (GbE) plus 4-port 10 Gigabit Ethernet (10GbE) solution that provides carrier-class features such as IPv4 and IPv6 routing, as well as advanced metro encapsulation protocols and advanced security mechanisms such as IPFix and large access control lists (ACLs) for user and flow-based authentication. The BCM56624 also includes advanced QoS features for service provider applications with a new dynamic adaptive memory buffer technology that provides better QoS and network performance. It also features large external address and security tables that scale to meet the demands of high performance equipment at the core of the network.
- The BCM56720 — a 4th generation StrataXGS HiGig switch fabric that provides half a terabit of packet switching capacity on a single chip and scales to achieve multi-terabits of capacity on a single backplane. It is compatible with the new StrataXGS 4 series of products as well as products from earlier StrataXGS architectures. This switch fabric also leverages the company’s HiGig stacking protocol and service aware flow control (SAFC).

- In November 2007, Broadcom introduced its BCM56820 24-port, multi-layer 10GbE switch solution for the data center and other high performance applications. Also designed in 65nm, the BCM56820 offers significant per port power savings over previous generation 10GbE switch products, providing greater density at a lower power.
