The VSC7422 is the industry’s first fully integrated 25-port Gigabit Ethernet (GE) switch with 12 copper PHYs in a single package. In conjunction with Microsemi’s 12-port PHY VSC8512 or VSC8522, a 25-port switch can be designed using only two ICs. The VSC7422 leverages Microsemi’s 65 nm technology, resulting in one of the most cost-effective and lowest power consumption solutions in the industry. It includes the most advanced IEEE 802.3az Energy Efficient Ethernet features for bringing green technology solutions to market. A rich set of Ethernet switching features, such as Layer 2 forwarding with VLAN and QoS processing, enables the delivery of differentiated services. The VSC7422 contains an 8051 CPU for light management of the switch. A comprehensive application software package is provided for LED control, loop indication, device overheat protection, and other enhanced functions.
