Datapath Systems, Inc. to Present Technical Advancements in Chip Design for the Digital Storage and ADSL Industries at ISSCC '99.LOS GATOS, Calif.--(BUSINESS WIRE)--Feb. 12, 1999-- Papers Represent Latest State-of-the-Art Technology For Read/Write Channel ICs and Analog Front Ends for ADSL See DSL. ADSL - Asymmetric Digital Subscriber Line Modems DataPath Systems, Inc., a leader in the design and development of complex, mixed-signal technology, will present three papers representing some of the latest advancements in the development of Trellis-coded EPRML EPRML Extended Partial Response Maximum Likelihood EPRML Enhanced Partial Response Maximum Likelihood read/write channel ICs and Analog Front Ends for the ADSL industry at the IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. International Solid-State Circuits Conference International Solid-State Circuits Conference is a global forum for presentation of advances in solid-state circuits and Systems-on-a-Chip. The Conference offers a unique opportunity for engineers working at the cutting edge of IC design to maintain technical currency, and to being held in San Francisco, Feb. 15-17, 1999. The first of the two papers on the read/write channel IC is A Trellis-Coded E(2)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. Digital Read/Write Channel IC. The TC-E(2)PRML read/write channel IC is capable of operating up to 400Mb/s and combines a rate of 8/9 trellis code with higher-order partial response target called E(2)PR4. The signal to noise ratio improvement of the TC-E(2)PRML system over the rate 16/17 EPRML and the 8/9 PRML system is 1.5 dB and 3 dB at normalized user density of 2.5. These numbers progressively increase to 2 dB and 6 dB as the user density increases to 3. In comparison to the major competitors, this IC demonstrates the highest level of performance for the lowest power dissipation in the industry. The second paper, A 3V 10-100 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. Continuous-Time Seventh-Order 0.05(Degree) Equiripple Linear-Phase Filter, demonstrates state-of-the-art developments for BiCMOS filter design. DataPath's latest advancement in this area increases the frequency to 100 MHz, the fastest in the industry, while maintaining a low power consumption. Both papers will be given during the disk drive signal processing session on Monday, Feb. 15 beginning at 1:30 p.m. The third paper, A CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. Analog Front End IC for DMT See DSL. ADSL, discusses DataPath's highly integrated CMOS AFE (Apple File Exchange) An earlier Macintosh utility that converted data files between Mac and PC formats. It also included a file translator between IBM's DCA format and MacWrite. , compliant with both the full ADSL T1E1.413 DMT standard and the emerging G.lite standard. The AFE achieves 14bit linearity in both RX and TX paths and input-referred noise better than -160dBm/Hz, from a single 5.0V supply. These noise and linearity specifications are necessary for an ADSL modem to operate at 1.5Mb/s on the longest lines and reach above 90% of installed copper connections. This paper will be given during the xDSL session on Tuesday, Feb. 16, beginning at 1:30 p.m. Company Overview DataPath Systems, Inc. is a privately-held company founded in 1994 by a team of highly skilled engineers with backgrounds in signal processing for digital storage and communications. The company's core competency is the design, development, and manufacture of complex mixed analog/digital chips for signal processing and communications applications.
