Vitesse Delivers Industry´s First Energy-Efficient Solutions for Ethernet-Based Electronics


    Networking equipment suppliers promoting green electronics
    portfolios can activate compelling, energy-efficient functionality
    within their Ethernet-based electronics via a simple software upgrade
    available today from Vitesse Semiconductor Corporation (Pink
    Sheets:VTSS). Vitesse is the first Ethernet silicon supplier to
    deliver energy saving features of up to 80-percent when fully
    linked-down using its widely-adopted SimpliPHY, SparX, and G-RocX IC
    solutions.

    Delivering green savings equivalent to over 400mW per port, all
    three of Vitesse´s Ethernet IC product families are enhanced with two
    advanced, energy savings technologies. The first, ActiPHY(TM), is an
    automatic power savings mode that can detect unused Ethernet ports on
    network devices and power them down or place them in stand-by mode.
    The second, PerfectReach(TM), is an intelligent algorithm that
    actively adjusts the power level needed based on cable length. Both of
    these features are already integrated into all SimpliPHY, SparX, and
    G-RocX devices currently in mass production and can be enabled via an
    eco-friendly software upgrade.

    New Functionality Bridges Industry Specifications

    The IEEE802.3 Ethernet specification does not specify a standby
    power level whenever a link is not established. Vitesse´s ActiPHY

    however, enables a physical layer Ethernet port to detect link loss
    and put the port into a sleep state, thereby reducing the port´s power
    in existing devices by well over 400mW. Using a proprietary energy
    detection circuit to filter random cable noise, ActiPHY detects the
    presence of link pulses, restores active power and puts the port back
    into normal operation. To ensure maximum interoperability when plugged
    into another Ethernet PHY with sleep capability, the device will wake
    up at a programmable rate and send a few link pulses to allow another
    sleeping device the opportunity to wake-up.

    PerfectReach is an intelligent algorithm that actively adjusts the
    power level needed based on cable length. IEEE802.3 Ethernet specifies
    10/100/1000BASE-T copper PHYs to operate at 100 meters. The standard
    also expects these same PHYs to communicate at its maximum power cable
    reach even if it is plugged into a cable that can be as short as a
    single meter. PerfectReach detects the presence of a shorter cable and
    then adaptively lowers the power level, saving energy for links
    shorter than the full 100 meters of cable length specified by IEEE
    standards.

    Ethernet OEMs Promoting Green Technology

    Broadening public awareness, surging network usage and adopting of
    global legislation has increased demand for network equipment that
    operates more efficiently and delivers a positive impact for
    businesses, consumers and the environment. OEMs are now answering the
    call by delivering products to this emerging green-conscious customer
    segment by incorporating Vitesse´s ActiPHY and PerfectReach
    technology.

    D-Link Systems, Inc. (D-LINK- TSEC) now offers Gigabit Home/SOHO
    switch products that not only comply with RoHS (Restriction of
    Hazardous Substances), but are the first to achieve energy efficiency.
    "Our environmentally friendly products have enabled eco-conscious
    customers to embrace and benefit from green concepts with regard to
    their connectivity," said A.J. Wang, CTO for D-Link Systems, Inc. "In
    a standard workday scenario, PCs are used for 10 hours a day, powered
    off for 14, and connected to a switch using 20 meter cables. D-Link´s
    Green Ethernet(TM) on 8-, 16-, and 24-port switch products, powered by
    Vitesse´s SparX products with ActiPHY and PerfectReach technologies

    helped us bring to market the industry´s first Green Ethernet 8-port
    10/100/1000BASE-T desktop switch that achieves power savings of up to
    80-percent."

    Corega, a global computer networking manufacturer based in Japan

    promotes greener practices as an organization and within the solutions
    it delivers. "In our original switching products, an IEEE 802.3
    Ethernet-compliant device that had no ports connected to a link still
    consumed nearly the comparable amount of power as a fully-utilized
    switch," said Sho Katoh, president of Corega. "By simply enabling
    Vitesse´s ActiPHY automatic link down power savings technology via
    software, we are now able to save our customers a maximum of 65.8% of
    electric power in the presence of unused Ethernet ports."
