The VSC8522-02 and VSC8522-04 devices contain 12 integrated Gigabit Ethernet (GE) 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 EcoEthernet IEEE 802.3az Energy Efficient Ethernet 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.
