"Enables network-wide Layer 2 MACsec encryption and preserves nanosecond-level IEEE 1588v2 network timing accuracy with a simple PHY upgrade.The quad port VSC8584 GbE PHY with Intellisec and VeriTime is ideal for securing cloud network applications including e-commerce, databases, collaboration, smart grid, video, and enterprise or government communications. Intellisec enables a realistic and affordable Layer 2 MACsec security solution. Intellisec is a patent-pending technology enabling IEEE 802.1AE MACsec encryption end-to-end over any network, including multi-operator and cloud-based networks, independent of the network's awareness of security protocols. Intellisec is not limited to traditional MACsec link-based box-to-box applications. Likewise, Intellisec scales easily with the number of interfaces delivering significant cost savings in network deployment.VeriTime is Microsemi's patent-pending timing technology that delivers the industry's most accurate IEEE 1588v2 timing implementation down to 4 ns. Integration of MACsec with IEEE 1588v2 time stamping in the PHY is an efficient and low cost method to protect data passing through the network while maintaining highly accurate time of day (ToD). For these applications, the device supports daisy-chaining of SPI interfaces for IEEE 1588v2 time stamping to reduce the number of pins required on a target ASIC, SoC or FPGA.VSC8584 supports Y.1731 OAM and MPLS-TP OAM for accurate delay measurement and performance monitoring. In addition, it includes dual recovered clock outputs for timing references in Synchronous Ethernet solutions. Using Microsemi's Ring Resiliency™ technology, the PHY switches between master and slave timing without interrupting the 1000BASE-T link."
