CD-G Decoder

CXD1807Q

Description

The CXD1807Q has functions to decode CD-G

commands written in the CD subcode and write

them into the DRAM to display them. It also has a

built-in RGB 4-bit D/A converter. By adding 256K

bits of DRAM and a video encoder, a CD graphics

system can be configured.

Functions

• Real-time correction of subcode errors

• Powerful protection circuit for subcode synchronization

• RAM for color look-up table

• Compatible with both NTSC and PAL

• 4-bit DAC for RGB

• 80-pin QFP
