Intel unveils specification for PC-networking cards By Mark Hachman Electronic Buyers' News (02/08/00, 03:30:31 PM EDT) SANTA CLARA, Calif. -- Intel Corp. here released a specification on Monday for the Communication and Networking Riser card, an outgrowth of its audio and communications strategy for the PC. In concept, the card leverages Intel's earlier work to develop anAudio/Modem Riser (AMR) card that is shipping in some PCs today, and which reserves the highest-value components for the motherboard. The new networking card takes the idea a step further by adding support for a LAN interface, Universal Serial Bus, and SMBus interface. Executives at Intel did not return phone calls by press time. Like the AMR card, the CNR was designed for cost and electrical considerations. By placing inexpensive, albeit electrically noisy, components on a separate card, the CNR is designed to cut costs and simplify motherboard manufacture and test. By accommodating either an on-board 10/100-Mbit/s or phone-line-networking PLC/PHY, the CNR card also addresses both home and commercial use, adding weight to Intel's commitment to home networking applications. In a similar fashion, the specification permits a basic AC'97 codec to be soldered directly to the motherboard, but allows for the addition of a second, higher-quality codec on the CNR card to give OEMs the option of offering two tiers of quality. "Native networking as a part of every PC is a key element of our e-home strategy," said Pat Gelsinger, vice president and general manager of Intel's Desktop Products Group. "The CNR specification gives OEMs greater flexibility in platform design and more options in reconciling PC connectivity features with international certification processes and manufacturer-specific requirements." Intel also made a key design change between the AMR and CNR cards. While the AMR supports one primary codec and up to three secondary analog codecs, the CNR card can support only one secondary codec. Intel added that the platform is able to accept only a single PLC/PHY in the entire system; placing more than one such chip either on the motherboard or CNR card may damage the networked devices, the company said. Cirrus Logic Inc., of Fremont Calif., ranked by analyst firm Mercury Research Inc. as the leading vendor of PC-audio ICs, announced a complementary CNR reference board today. The board is designed around Cirrus' established line of Crystal Audio PC-audio codecs, but with software drivers for Intel-compatible operating systems. semibiznews.com
