VSC8574 Quad Port Dual Media QSGMII/SGMII GbE PHY with IEEE 1588 Microsemis new GbE PHY simpli es Synchronous Ethernet and Highlights IEEE1588 timing in Carrier Ethernet designs. Single and two-step IEEE 1588v2 time stamping over encapsulated links including VSC8574 is the next-generation Carrier Ethernet Gigabit PHY MPLS and PBB transceiver designed to simplify the support of fully traceable timing MPLS and Ethernet Y.1731 OAM support across Gigabit Ethernet backhaul devices, cellular base stations, and other timing-critical platforms. VSC8574 supports four dual media EcoEthernet 2.0 green technology for energy ef ciency copper/ ber ports with SGMII and QSGMII MAC interfaces. Recovered clock outputs and an integrated IEEE 1588 timing packet engine enable Applications the VSC8574 device to meet the demands of applications requiring highly precise timing, without adding unnecessary complexity or Wireless backhaul systems increased cost to the design. Carrier Ethernet cellular base stations To meet Carrier demands for redundancy, the VSC8574 device has dual Industrial automation systems 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 IEEE 1588, VSC8574 supports various encapsulation links including IP over 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. Microsemis innovative EcoEthernet 2.0 technology supports Energy Ef cient 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.
