1GE-PHYs

Quad Port Dual Media QSGMII/SGMII GbE PHY with VeriTimeâ„¢

Part of the SynchroPHY suite of 1GE, 10GE and 10GE OTN devices, the VSC8574 is the next-generation Carrier Ethernet Gigabit PHY transceiver designed to simplify the support of fully traceable timing across Gigabit Ethernet backhaul devices, cellular base stations, and other timing-critical platforms. The device features VeriTime, Vitesse’s patent-pending distributed timing technology that delivers the industry’s most accurate IEEE 1588v2 timing implementation. VSC8574 supports four dual media copper/fiber ports with SGMII and QSGMII MAC interfaces. Recovered clock outputs and an integrated VeriTime IEEE 1588v2 timing packet engine enable the VSC8574 device to meet the demands of applications requiring highly precise timing, without adding unnecessary complexity or increased cost to the design. To meet Carrier demands for redundancy, the VSC8574 device has dual recovered clock outputs for primary and secondary timing references for Synchronous Ethernet solutions. Programmable clock squelch control is included for inhibiting undesirable clocks 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 1000BASE-T link. VSC8574 has integrated temperature monitoring and is ideal for high-temperature applications. Vitesse’s innovative EcoEthernet 2.0 technology supports Energy Efficient Ethernet (EEE) through ActiPHY™ automatic link powerdown and the PerfectReach™ intelligent algorithm that adjusts power based on cable length. VSC8574 further supports reduced power consumption in all link operating speeds.
