VSC8522-04

• Supports IEEE 802.3az and green energy

• Lowest BOM solution requires only one IC

• Three QSGMII MAC interface and one

Applications

• Unmanaged and Lightly Managed Ethernet

The VSC7422-04 is the industry’s fi rst fully integrated 25-port

Gigabit Ethernet switch with 12 copper PHYs in a single package. In

conjunction with Microsemi’s 12-port VSC8512-03 or VSC8522-04, a

25-port switch can be designed using only two ICs.

The VSC7422-04 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 Ethernet energy effi ciency

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

25-Port Layer 2 Gigabit Ethernet Switch with 12 Fully Integrated Copper PHYs

Best-in-Class Power Consumption

• Lowest power 25-port Gigabit Ethernet switch available in the

market

• Green energy effi ciency modes including ActiPHY™, Perfect-

Reach™, and Draft IEEE 802.3az

• Integrated 250 MHz 8051 CPU with 64 KB internal storage

• Serial interface for external CPU register access

• Device overheat protection

• Hardware loop detection

• Integrated fan controller

• 8 K MAC addresses and 4 K VLAN support

• Push/pop VLAN tag

• Supports IEEE 1149.1 JTAG boundary scan, IEEE 1149.6

JTAG, 1 Gbps SGMII, and 100BASE-FX and 1000BASE-X

Layer 2 Switching

• Independent and shared VLAN learning

• Jumbo frame support up to 12.2 kilobytes with per-port

programmable MTU
