Low-power, small form-factor Cu PHY with IEEE 802.3az Energy Efficient Ethernet (EEE) and Wake-on-LAN (WoL), with widest I/O LVCMOS support.  The VSC8531 device, offered in a tiny 6 mm x 6 mm single-row QFN package, is designed for space-constrained 10/100/1000BASE-T applications. It features integrated line-side termination to conserve board space, lower EMI, and improve system performance. Additionally, integrated RGMII version 2.0 standard timing compliant compensation eliminates the need for on-board delay lines. The device supports the industry’s widest range of LVCMOS levels for a parallel MAC interface including 1.5 V, 1.8 V, 2.5 V, and 3.3 V, as well as 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V support on the MDIO/MDC interface.  VSC8531 includes Microchip’s EcoEthernet™ 2.0 technology with Energy Efficient Ethernet and power saving features to reduce power based on link state and cable reach. It optimizes power consumption at all link operating speeds, and features Wake-on-LAN power management using magic packets.
