The device features VeriTime, Vitesses patent-pending distributed timing technology that delivers the MPLS and PBB industrys most accurate IEEE 1588v2 timing implementation. VSC8574 supports four dual media copper/fiber ports with SGMII and MPLS and Ethernet Y.1731 QSGMII MAC interfaces. Recovered clock outputs and an integrated VeriTime IEEE 1588v2 timing packet engine enable the VSC8574 OAM support device to meet the demands of applications requiring highly precise timing, without adding unnecessary complexity or increased cost to EcoEthernet 2.0 green the design. To meet Carrier demands for redundancy, the VSC8574 device has dual recovered clock outputs for primary and secondary technology for energy timing references for Synchronous Ethernet solutions. Programmable clock squelch control is included for inhibiting undesirable clocks efficiency from propagating and preventing timing loops. In addition to identifying PTP Y.1731 in Ethernet and IPv4/6 over Ethernet per IEEE1588, VSC8574 supports various encapsulation links including IPover MPLS, Ethernet pseudowire over MPLS/MPLS-TP, QinQ, and MAC-in-MAC. VSC8574 supports ring resiliency, a feature that enables PHY ports to switch between master and slave timing without interrupting the Applications 1000BASE-T link. VSC8574 has integrated temperature monitoring and is ideal for high-temperature applications. Vitesses innovative Industrial automation systems EcoEthernet 2.0 technology supports Energy Efficient Ethernet (EEE) through ActiPHY automatic link powerdown and the PerfectReach Wireless backhaul solutions intelligent algorithm that adjusts power based on cable length. VSC8574 further supports reduced power consumption in all link operating speeds.
