VSC7423 is one of the most versatile Gigabit Ethernet (GE) switches in the industry. It integrates seven GMII ports, five GE 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 (CE) 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 IEEE 1588, Microsemi's patent-pending timing technology that delivers the industry's most accurate IEEE1588 network timing and synchronization implementation. The VSC7423 device can be configured to support combinations of up to five SGMII ports, five GE 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 416MHz MIPS 32-bit CPU with DDR2 external memory and DMA-based frame extraction and insertion supports VeriTime IEEE 1588, Ethernet OAM, and performance monitoring. VSC7423 meets IEEE802.3az Energy Efficient Ethernet requirements for green, SyncE operation with Microsemi's ActiPHY and PerfectReach modes. A comprehensive application programming interface (API) and software package are provided for CE applications. The software package integrates easily with third-party software, preserving existing software investments while adding new, enhanced carrier functionality.
