A new front-end signal-processing LSI for HD DVD

This work presents a front-end LSI using 0.13 /spl mu/m-process developed for HD DVD disc drives. HD DVD is a recently proposed format for optical discs, in which a blue laser is adopted and high-density recording of over 15 GB per side is achieved. The LSI chip consists of 3 subsystems: partial response maximum likelihood (PRML) read channel subsystem, servo control subsystem and memory control subsystem. Using this LSI, we have also developed a HD DVD player and verified the performance to be sufficient for high-definition movies or other content. The ability to play back high-definition quality movies proves the basic potential of this LSI.
