VSC8512
12-Port 10/100/1000BASE-T PHY with SGMII and QSGMII MAC Interface
Microsemi’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 Microsemi’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.
