SM9403BM NIPPON PRECISION CIRCUITS INC. DVDRAM Servo-ampliļ¬er LSI OVERVIEW The SM9403BM is a DVDROM and DVDRAM servo preprocessor LSI, designed for double-speed format DVDROM and DVDRAM drives. The SM9403BM is fabricated using a BiCMOS process, and incorporates an analog signal processing circuit that generates signals needed by the digital servo processor, a DPD signal processing circuit (DVDROM), and a CAPA (Complementary Allocated Pit Address) detection circuit (DVDRAM) all in a single chip. It operates from a single 5 V supply, and is available in 36-pin plastic SSOP packages.
