VSC8512XJG-02

12-Port 10/100/1000BASE-T PHY with SGMII and QSGMII MAC Interface. Vitesse’s next-generation triple-speed PHY delivers the industry’s lowest power Gigabit Ethernet physical media solution. The VSC8512 is the industry’s first 12-port Gigabit Ethernet copper PHY solution in a single package. The VSC8512 leverages Vitesse’s new 65 nm SimpliPHY technology, resulting in the one of the most cost-effective and lowest power consumption devices in the industry. The single chip solution includes the most advanced Ethernet energy efficiency features for bringing green technology solutions to market. The VSC8512 employs the latest QSGMII MAC interface to reduce PCB routing to a MAC, switch, or ASIC chip. The VSC8512 is ideal for high-density switch and router applications, enabling Ethernet multiport systems to achieve very low system Bill of Material (BOM) costs, reducing overall production costs for more cost-effective deployments. SimpliPHY devices use field-proven, fully adaptive equalization and innovative timing recovery algorithms for unparalleled noise tolerance performance. SimpliPHY devices are based on patented, fully balanced voltage-mode line driver technology, which allows lower cost magnetics to be used.
