PRODUCT BRIEF
VSC7421-04
17-Port Layer 2 Gigabit Ethernet Switch with
12 Fully Integrated Copper PHYs
Highlights
•
Supports IEEE 802.3az and
green energy efficiency modes
with ActiPHY and
Vitesse’s next-generation switch device delivers the
industry’s lowest power GbE switching solution.
PerfectReach
•
•
Lowest BOM solution requires
only one IC
VSC7421-04 is the industry’s first fully integrated 17-port Gigabit
Ethernet switch with eight copper PHYs in a single package. In
conjunction with Vitesse’s 4-port VSC8514-03 or VSC8664-03 devices,
a 17-port switch can be designed using only two ICs.
One QSGMII MAC interface
and up to four SGMII ports with
100 Mbps and 1 Gbps fiber
support
The device 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.
Applications
•
Unmanaged and Lightly
A rich set of Ethernet switching features, such as Layer 2 forwarding
with VLAN and QoS processing, enables the delivery of differentiated
services. The VSC7421-04 device contains an 8051 CPU for light
management of the switch.
Managed Ethernet switches
•
•
Industrial switches and routers
Customer premises equipment
(CPE) and outdoor equipment
A comprehensive application software package is provided for LED
control, loop indication, device overheat protection, and other enhanced
functions.
