Marvell Offers Second-Generation "Plug and Play" Fast Ethernet Transceivers for the Small Office/Home Office.Business Editors, High-Tech Writers SUNNYVALE, Calif.--(BUSINESS WIRE)--August 7, 2000 Marvell (Nasdaq:MRVL), a technology leader in the development of broadband mixed-signal and digital signal processing See DSP. Digital Signal Processing - (DSP) Computer manipulation of analog signals (commonly sound or image) which have been converted to digital form (sampled). (DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive ) technology solutions, today announced its second-generation DSP-based Hex and Octal Fast Ethernet transceivers. These feature-enhanced devices provide Small Office/Home Office See SOHO. (SOHO Soho (sōhō`, sə–), district of Westminster, London, England, known for its continental restaurants. Once a fashionable quarter, it became popular among writers and artists in the 19th cent. ) end users with a true "plug and play" networking solution. The introduction of Marvell's second-generation Hex and Octal Fast Ethernet transceivers follows its volume-production first-generation devices, whose introduction last September marked a significant milestone in the networking industry, breaking new ground in low power dissipation, higher Signal-to-Noise ratios and superior distance coverage/connection reliability. Marvell's advanced 0.22 micron DSP-based Hex and Octal Fast Ethernet transceivers, the 88E3061 and the 88E3081, offer several new advantages. The devices provide end-users with a single cable solution for true "plug and play" networking installation with the Automatic MDI/MDIX crossover feature. This feature enables Marvell's Fast Ethernet transceiver to automatically and transparently detect and correct incorrectly wired cables, making installation, debug and maintenance of the network easier and less expensive for the end user. Marvell is first to market with devices that support the Source Synchronous option of Cisco's latest Serial Media Independent Interface (SMII SMII Serial Media Independent Interface ) specification. This allows for simplified system design by reducing the I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output pin count between the transceiver and the Media Access Controller (MAC)/Switch. Jumbo frame support (handling large data packets) enabling effective utilization of networking bandwidth. Low power consumption allowing for more reliable networking systems and higher port density. Simplified board design with fewer external components providing lower overall system cost. Marvell's DSP-based Fast Ethernet transceivers with advanced functionality address the networking requirements of the SOHO market where ease of use, cost and low power are essential. The DSP technology originates from the company's leading-edge Gigabit Ethernet solutions. Marvell's recent introduction of the Alaska(TM) family of Gigabit Ethernet transceivers has proven itself as the de facto solution for the gigabit market segment by demonstrating the industry's lowest power dissipation at 1.8 Watts per 10/100/1000 channel, the smallest form factor packaging and industry-leading performance. The Alaska family solution addresses the high-bandwidth requirements of the rapidly growing enterprise-class and business desktop markets. "Marvell's high performance, low power and easy-to-use 10/100 Ethernet switches provides the SOHO market with a simplified and effective networking solution. Our broad portfolio of advanced Fast Ethernet transceivers and industry-leading Alaska family of Gigabit Ethernet transceivers for the enterprise-class and business desktop markets has made Marvell the `one-stop shop' for the vast Ethernet market," stated Weili Dai, Marvell's Executive Vice President and General Manager of the Data Communications Group. 88E3061/88E3081 Fast Ethernet Transceiver Product Information Marvell's 88E3061 Hex and 88E3081 Octal Fast Ethernet transceivers leverage technology developed through Marvell's first generation Physical Layer (PHY See physical layer and physical. ) transceivers as well as through its family of Alaska Gigabit Ethernet transceiver products and four generations of Partial Response Maximum Likelihood (storage) Partial Response Maximum Likelihood - (PRML) A method for converting the weak analog signal from the head of a magnetic disk drive into a digital signal. PRML attempts to correctly interpret even small changes in the analog signal, whereas peak detection relies on fixed (PRML (Partial Response Maximum Likelihood) A technique used to differentiate a valid signal from noise by measuring the rate of change at various intervals of the rising waveform. ) read channels designed for the data storage market. The 88E3061/88E3081 is a six/eight port physical layer device for Ethernet 100BASE-X and 10BASE-T applications. It contains all of the active circuitry to convert data streams to and from six/eight MACS and twisted pair cables in full or half duplex mode. Marvell's 88E3061 and 88E3081 transceivers support either the Reduced Media Independent Interface Reduced Media Independent Interface (RMII) is a standard that addresses the connection of Ethernet physical layer transceivers (PHY) to Ethernet switches. It reduces the number of signals/pins required for connecting to the PHY from 16 (for an MII-compliant interface) to 6 to 10. (RMII RMII Reduced Media-Independent Interface RMII Rocky Mountain Internet Inc. ) or the Source Synchronous option of the Serial Media Independent Interface (SMII) for connection to very high port count switch chips. Source Synchronous SMII (SSMII SSMII Source Synchronous Media Independent Interface ) is designed for applications requiring a trace delay of more than 1 ns. The receive and transmit paths in source synchronous mode operate identically to the SMII interface, and is backward-compatible to SMII version 1.2. Marvell's Hex and Octal PHY transceivers also support Auto-Media Independent Interface crossover (Auto-MDI/MDIX feature) for 100BASE-TX and 10BASE-T connections. The PHY interface can automatically determine whether or not it needs to cross over between pairs so that an external crossover cable is not required. If the 88E3061/88E3081 interoperates with a device that cannot automatically correct for crossover, the PHY makes the necessary adjustment prior to commencing Auto-Negotiation. Last, Marvell's Hex and Octal PHY transceivers provide Jumbo frame support up to 10Kbytes with large frequency offset tolerance of +/- 150 ppm. This feature allows the transceiver to support applications that demand a larger packet size, effectively utilizing networking bandwidth. Availability Marvell's 88E3061 Hex and 88E3081 Octal Fast Ethernet transceivers are available today and are offered in 128 and 208-pin PQFP (Plastic Quad Flat Package) Refers to many varieties of QFP chip packages, which are molded in plastic.
