VSC8572 Dual Port Dual Media RGMII/SGMII GbE PHY with IEEE 1588 Microsemi's new GbE PHY simplifies Synchronous Ethernet and IEEE 1588 timing in Carrier Ethernet designs. VSC8572 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. VSC8572 supports two dual media copper/fiber ports with RGMII and SGMII MAC interfaces. Recovered clock outputs and an integrated IEEE 1588 timing packet engine enable the VSC8572 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 VSC8572 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. Highlights * Single and two-step IEEE 1588v2 time stamping over encapsulated links including MPLS and PBB * MPLS and Ethernet Y.1731 OAM support * EcoEthernetTM 2.0 green technology for energy efficiency Applications * Wireless backhaul systems * Carrier Ethernet cellular base stations * Industrial automation systems In addition to identifying PTP Y.1731 in Ethernet and IPv4/6 over Ethernet per IEEE 1588, VSC8572 supports various encapsulation links including IP over MPLS, Ethernet pseudowire over MPLS/MPLSTP, QinQ, and MAC-in-MAC. VSC8572 supports ring resiliency, a feature that enables PHY ports to switch between master and slave timing without interrupting the 1000BASE-T link. VSC8572 has integrated temperature monitoring and is ideal for high-temperature applications. Microsemi's innovative EcoEthernet 2.0 technology supports Energy Efficient Ethernet (EEE) through ActiPHYTM automatic link powerdown and the PerfectReachTM intelligent algorithm that adjusts power based on cable length. VSC8572 further supports reduced power consumption in all link operating speeds.
