VSC7423
7-Port, Layer-2 Gigabit Ethernet Switch with VeriTime™ , 5 Integrated Copper PHYs, and Embedded 32-bit CPU
Microsemi's next-generation Ethernet switch delivers a comprehensive,
end-to-end Carrier Ethernet solution.
VSC7423 is one of the most versatile GbE switches in the industry. It
integrates seven SGMII ports, five Gigabit Ethernet copper PHYs, and
an embedded CPU into a single package. It also provides full support
for MEF service delivery, network OAM, and Synchronous Ethernet
(SyncE) timing. It is ideal for Telecom and Carrier Ethernet applications,
Mobile and Microwave backhaul applications, and for provider service
demarcation points in Edge and Access devices.
For critical network timing, the VSC7423 device uses VeriTime™,
Microsemi’s patent-pending distributed timing technology that delivers
the industry’s most accurate IEEE 1588v2 implementation.
The VSC7423 device can be configured to support combinations of up
to five SGMII ports, five GbE Cu PHYs, and two 1G/2.5G SGMII uplink
ports. One of the SGMII ports can be dedicated to the CPU for packet
insertion and extraction. Its powerful, embedded 416 MHz MIPS 32-bit
CPU with DDR2 external memory and DMA-based frame extraction
and insertion supports VeriTime™, Ethernet OAM, and performance
monitoring. VSC7423 meets IEEE 802.3az requirements for green,
SyncE operation with Microsemi’s ActiPHY™ and PerfectReach™
modes.
A comprehensive application programming interface (API) and software
package are provided for Carrier Ethernet applications. The software
package integrates easily with third-party software, preserving existing
software investments while adding new, enhanced carrier functionality.
