Overview

The LC897127K is a CD-ROM decoder that includes an

on-chip DVD interface. Since the LC897127K also

includes an on-chip SCSI interface, it can be used to

implement a SCSI-compatible DVD-ROM drive simply

by combining it with a DVD decoder. It can also operate

as an independent SPC functional unit.

Functions
