Shenzhen Mingjiada Electronics Co., Ltd Supply Ethernet Transceivers VSC8514XMK-14 and VSC8514XMK-11 4-Port GbE Cu PHY with QSGMII

VSC8514XMK-14 and VSC8514XMK-11 Device Description:

The VSC8514 is a four-port Gigabit Ethernet (GE) PHY that operates at low power for energy-efficient broadband gateways, data centres and enterprise networks. The device supports TDM backhaul, wireless base stations, and other carrier applications with two Synchronous Ethernet (SyncE) recovery clock outputs.The VSC8514 device features Microchip's innovative EcoEthernet™ IEEE 802.3az Energy Efficient Ethernet technology, which supports Energy Efficient Ethernet (EEE), ActiPHY™ automatic link power-down, and PerfectReach™ (a new technology that enables the use of a single Ethernet cable). PerfectReach™, an intelligent algorithm that adjusts power based on cable length.The VSC8514 device optimises power consumption at all link operating speeds. Adjustable LED brightness control further reduces end-user power consumption.
