Abstract

CD-ROM systems use a simple slicer for data detection, but the increased intersymbol interference in DVD signals makes a PRML system advantageous. A first-generation fully-integrated 4.5/spl times/ DVD-ROM and CD-ROM system includes data channel, servo, decoder, error correction, ATAPI, and microcontroller interfaces. Analog input signals are quickly converted to digital signals throughout the chip to remove performance variation and to take advantage of process scaling. This mixed signal device is 73 mm/sup 2/ with 1.8 M transistors in 0.35 /spl mu/m CMOS.
