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.
