Datapath Systems, Inc. to Present Technical Advancements in Chip Design for the Digital Storage and ADSL Industries at ISSCC '99
Papers Represent Latest State-of-the-Art Technology For Read/Write Channel ICs and Analog Front Ends for ADSL Modems
LOS GATOS, Calif.--(BUSINESS WIRE)--Feb. 12, 1999-- 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 read/write channel ICs and Analog Front Ends for the ADSL industry at the IEEE International Solid-State Circuits Conference 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 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 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 Analog Front End IC for DMT ADSL, discusses DataPath's highly integrated CMOS AFE, 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.
