The VSC7425 is the industry’s first fully integrated 18-port Gigabit Ethernet (GE) switch with 12 copper PHYs in a single package. In conjunction with 4-port PHY VSC8514, an 18-port switch can be designed using only two ICs. The VSC7425 leverages new 65 nm SimpliPHY technology, resulting in the one of the most cost-effective and lowest power consumption devices in the industry. The dual chip solution combines the most advanced IEEE 802.3az Energy Efficient Ethernet features for bringing green technology solutions to market. The VSC7425 provides a rich set of Small Medium Enterprise (SME) Ethernet switching features such as Layer-2 forwarding with advanced TCAM-based VLAN and QoS processing, enabling the delivery of differentiated services. Security is ensured through frame processing using a TCAM-based Virtualized Content Aware Processor (VCAP-II). The VSC7425 contains a powerful 416 MHz CPU, enabling full management of the switch. A comprehensive application programming interface (API) and software development package is available for Layer-2 Managed Ethernet applications for faster time-to-market. The software API package integrates easily with third-party software, preserving existing software investments.
