Switch ICs enable up to 48 1-GB copper ports

The VSC7432 (E-StaX-III-48) and VSC7434 (E-StaX-III-68) high-density Gigabit Ethernet switching ICs are said to deliver a 30% power reduction over competitive solutions in a three-chip design. The VSC7432 enables a three-chip solution with 24 1-Gbyte copper ports and dual 10-Gbyte ports, or a six-chip solution with 48 1-Gbyte copper ports. The VSC7434 enables a three-chip solution with 24 1-Gbyte copper ports and quad 10-Gbyte ports, or a six-chip solution with 48 1-Gbyte ports and quad 10-Gbyte ports.

The ICs have a 416-MHz MIPS processor, a multistage TCAM, and unique stacking ports that allow connectivity between switches and over very-cost-efficient HDMI-like cables with up to 12-Gbyte full-duplex traffic forwarding. The E-StaX-III switch engines provide fast forwarding with a simplified software management environment, including a single point of management that can oversee up to 768 1-Gbyte ports and 32 10-Gyte ports.
