VSC8522
12-Port 10/100/1000BASE-T PHY with QSGMII MAC Interfaces
Microsemi’s next-generation triple-speed PHY delivers the industry’s
lowest power Gigabit Ethernet physical media solution.
The VSC8522-02 and VSC8522-04 devices contain 12 integrated
Gigabit Ethernet (GbE) PHYs with a power efficient voltage-mode
design, all within a single package. They leverage Microsemi’s 65 nm
technology, resulting in one of the most cost-effective and lowest power
consumption solutions in the industry. They include the most advanced
Ethernet energy efficiency features for bringing green technology
solutions to market.
The devices employ the latest QSGMII MAC interfaces to reduce PCB
routing to a MAC, switch, or ASIC chip. Ideal for high-density switch and
router applications, these devices enable Ethernet multiport systems to
achieve very low system Bill of Material (BOM) costs, reducing overall
production costs for more cost-effective deployments.
The devices use field-proven, fully adaptive equalization and innovative
timing recovery algorithms for unparalleled noise tolerance performance.
In addition, they are based on patented, fully balanced voltage-mode
line driver technology, which allows lower cost magnetics to be used.
