Marvell Announces High Performance Mixed-Signal Integrated Circuits for the Mass Storage Market.SUNNYVALE, Calif.--(BUSINESS WIRE)--Aug. 25, 1998--Marvell Semiconductor, Inc., today announced the availability of two new families of high-performance, read channel integrated circuits for the mass storage market. The 88C3000 and the 88C3100 are advanced 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. (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 ) mixed-signal solutions, based on Marvell's unique MSP (1) (Management Service Provider or Managed Service Provider) An organization that manages a customer's computer systems and networks which are either located on the customer's premises or at a third-party datacenter. (TM) technology. This proprietary technology makes it possible to design high frequency mixed-signal ICs in 100 percent digital 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. . Marvell's read channel products respond to the disk drive industry's broadest requirements for advanced PRML development. Both 88C3000 and 88C3100 product families match all the requirements of enterprise class, mobile and desktop applications. The devices combine faster data rates, superior areal disk density, low power dissipation and low cost. In addition, Marvell's MSP technology ensures all the benefits of mainstream CMOS including high performance, low cost, easy manufacturability, and high yield for high-volume production. The design architecture also provides the advantages of easy migration to smaller and faster chips with excellent time-to-market performance. "Our PRML products also are developed with future system-on-chip technology in mind," said Massoud Dabir, vice president marketing for Marvell. "The small die size, low power, high test coverage and mainstream CMOS process will allow disk drive manufacturers to start developing a single-chip solution for their drives today." The 88C3000 is designed in 0.35 micron CMOS process. It has a selectable PR4 and EPR EPR Electron Paramagnetic Resonance EPR Extended Producer Responsibility EPR Electronic Patient Record(s) EPR Emergency Preparedness and Response (US DHS) EPR Endpoint Reference EPR Ethylene-Propylene Rubber 4 Viterbi with 8/9 or 16/17 ENDEC supporting high data rates up to 350 Mb/s. The 88C3100 shares the design architecture and 0.35 micron CMOS of the 88C3000. It differs significantly from the 88C3000 in its Viterbi detection and encoding scheme. Test data shows the 88C3100, operating at 3.0 user bit density (UBD UBD - User Brain Damage ) with Noise Predictive Viterbi (NPV NPV See: Net present value ) and Trellis code selected, has a 2dB gain in signal-to-noise ratio (SNR See signal-to-noise ratio. SNR - signal-to-noise ratio ) over EPRML EPRML Extended Partial Response Maximum Likelihood EPRML Enhanced Partial Response Maximum Likelihood .
