PRODUCT BRIEF
VSC7422-04
25-Port Layer 2 Gigabit Ethernet Switch with
12 Fully Integrated Copper PHYs
Vitesse’s next-generation switch device delivers the
industry’s lowest power GbE switching solution.
The VSC7422-04 is the industry’s first fully integrated 25-port Gigabit
Ethernet switch with 12 copper PHYs in a single package. In conjunction
with Vitesse’s 12-port VSC8512-03 or VSC8522-04, a 25-port switch
can be designed using only two ICs.
The VSC7422-04 leverages Vitesse’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 Ethernet energy efficiency
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 VSC7422-04 device 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.
