VSC8504
Quad Port QSGMII Dual Media PHY with EEE Support
Microsemi’s new GbE PHY with award-winning EcoEthernet™
technology delivers best-in-class power consumption for QSGMII
designs.
VSC8504 is a quad port Gigabit Ethernet PHY with Microsemi's
next-generation EcoEthernet green technology for optimizing power
in Enterprise networks, data centers, and consumer electronics.
VSC8504 supports four dual media copper/fiber ports with QSGMII
MAC interfaces, delivering Carrier-quality Synchronous Ethernet for TDM
backhaul links, cellular base stations, and other SyncE applications
VSC8504 features Microsemi’s innovative EcoEthernet 2.0 technology
that supports Energy Efficient Ethernet (EEE) through ActiPHY™
automatic link powerdown and the PerfectReach™ intelligent algorithm
that adjusts power based on cable length.
The VSC8504 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.
