VSC8552 is a dual port Gigabit Ethernet PHY with Microsemi's next-

generation EcoEthernet green technology for optimizing power in

Enterprise networks, data centers, and consumer electronics, while

providing support for legacy RGMII devices. VSC8552 supports two

dual media copper/fi ber ports with RGMII, SGMII, and QSGMII MAC

interfaces, delivering Carrier-quality Synchronous Ethernet for TDM

backhaul links, cellular base stations, and other SyncE applications.

VSC8552 features Microsem’s innovative EcoEthernet 2.0 technology

that supports Energy Effi cient Ethernet (EEE), ActiPHY™ automatic link

powerdown, and the PerfectReach™ intelligent algorithm that adjusts
