SM9403BM
DVDRAM Servo-amplifier 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.
