VSC8552 is a dual port Gigabit Ethernet (GE) PHY with Microchip's next-generation EcoEthernet™ IEEE 802.3az Energy Efficient Ethernet 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/fiber ports with RGMII, SGMII, and QSGMII MAC interfaces, delivering Carrier-quality Synchronous Ethernet (Sync E) for TDM backhaul links, cellular base stations, and other SyncE applications. VSC8552 features Microchip’s innovative EcoEthernet technology that supports Energy Efficient Ethernet (EEE), ActiPHY™ automatic link powerdown, and the PerfectReach™ intelligent algorithm that adjusts power based on cable length. The VSC8552 device optimizes power consumption in all link operating speeds. It includes integrated temperature monitoring and smart fan control for extending system life and reducing BOM costs. Adjustable LED brightness control further reduces power consumption for end users.
